Online first-person shooter in 3D audio

Zero Hour Assault

Footsteps on gravel behind you. A window breaks two houses down. A helicopter is coming in with supplies, and you are not the only one who heard it. Zero Hour Assault is a fast online shooter played entirely by ear: you aim, move, drive and fight with sound alone, against real players from around the world.

Drop into a match in one of twenty-two modes, or parachute into Brackenford, an open city where the fight never stops. It is free to play, and it is built from the first line for blind and visually impaired players.

Message of the day

Zero Hour Assault is back, and it is bigger than ever! Hello everyone, Zero Hour Assault 2.0.0 is out now. This is the biggest update in the history of the game, built on a completely new engine. First, the most important news: nobody lost anything. Your accounts, characters, groups, communities, bases, items and zero tokens are all exactly where you left them, on both the computer and the mobile server. Just log in and play. To give everyone a fresh start, we have also lifted every ban on both servers. Everybody gets a second chance. Please use it well. Download: Windows: https://audiowander.com/zero_hour_assault.zip Android (Google Play): https://play.google.com/store/apps/details?id=com.nbmstudios.zero_hour_assault iPhone: the update is coming to the App Store very soon. Website: https://audiowander.com/zero-hour-assault.php One small thing: to keep every account safe, the first time you log in, the game mails a code to your e-mail address and asks for it once. After that you log in exactly as before. Please make sure you can open the e-mail address of your account. And when you loged in, please change your password if you want, to keep your account safe. A few words from us: We owe you an apology. For a long time we left you alone with the game, with too few updates and too little care. We are truly sorry for that. That time is over: we are back, and we are here to stay. Zero Hour Assault belongs to us. We hold the license of the game, and we have already taken action against the copies of it that are being shared as other games. The real Zero Hour Assault is the one you get from the links above. The staff team will no longer be made of random people. From now on the team will be careful, fair and honest, and cheating by staff will not be tolerated. If you see something wrong, report it from the game menu and we will look at it. Your voice matters. Every suggestion will be read and listened to. Write it in this group or send a ticket from the game. Many of the new features below came from players. The top 10 new features: 1. Brackenford, a brand new freedom fight city: about 60 buildings to enter, stairs up to the roofs, an underground railway, around 220 chests, 735 windows you can break, storms, airdrops and helicopter extractions. 2. Nine new match modes: Battle Royale, Search and Destroy, Team Deathmatch, Kill Confirmed, Hardpoint, Gun Game, Infected, Blackout and Squad Rounds. Computer-controlled fighters fill the empty seats, so you can always start a match. 3. Zero Plus: player levels from 1 to 100 with prestige stars, a monthly Season Pass, daily and weekly missions, more than 50 achievements, titles, badges and kill signatures. 4. Ranked play with eight divisions from Iron to Grandmaster, a bounty board, rivals and many leaderboards. 5. Real combat: walls stop every bullet, and instead of dying at once you are knocked down, and your friends can lift you back up. 6. New weapons: the AK-47, MKEK MPT-76, Tayfun, M1 Garand and the KS-123 shotgun, with a weapon guide that compares them. 7. Motors and bikes are back, with a dashboard, nitro, locks, repairs and sprint trials. 8. More than 20 new items, among them the med kit, smoke grenade, flashbang, frag grenade, decoy, poison vial, silent boots and thermal scanner. 9. An auction house, weekly group wars, base alarms, secret safes and a trust list for your base door. 10. Fair play for everyone: every character has the same health, speed and damage, the server checks walls and falls, alt accounts cannot pass tokens or loot, and paying never gives combat power. And that is only the top 10. Since the update work began, more than 400 new features, nearly 300 improvements and more than 100 fixes went into the game, over 800 changes in total. You also get daily rewards, a new lobby with a shooting range, an arena announcer, server events every 3 hours, and full Arabic, Spanish, Portuguese and Turkish translations. The full list is in the game. Thank you for staying with us. See you on the battlefield! NBM Studios

The same leaderboards you find in the game menu under Statistics, Ranked play and Progress, refreshed every five minutes. Repeated kills of the same player inside a few minutes do not count, so a place here has to be earned in real fights.

What is in the game

Everything below is in the game today.

Twenty-two match modes

Create a public or private match from the lobby, pick the mode and the team size, and start. Empty seats can be filled with computer-controlled fighters, so a match can begin even when you are alone. You can also watch any running match.

Nine new modes

  • Battle royale. Everyone starts with a pistol and loots the rest. The safe zone shrinks in six phases, and you hear how far and which way to run.
  • Search and destroy. Rounds without respawn. Attackers plant the spike on site A or B, defenders defuse it. First team to four rounds wins.
  • Team deathmatch. Respawn after every death. First team to 30 kills, or the best team after ten minutes.
  • Kill confirmed. Every death drops a beeping tag. Your team only scores by picking up the tags of its kills.
  • Hardpoint. Hold the hill for a point a second. The hill pings, and moves every 60 seconds.
  • Gun game. Every kill hands you the next of ten weapons. The last one is the knife.
  • Infected. One player turns, with a sword. Everyone they kill joins them. Survivors win if one of them lasts four minutes.
  • Blackout. Everyone for themselves in a dark arena: no footsteps, no player lists, no scopes. Find the beeping light switch for 25 seconds of light. Most rounds won wins.
  • Squad rounds. Two teams, rounds without respawn, and everyone fights with the same weapon each round. First team to four rounds wins.

In these modes everyone gets the same fixed equipment, so skill decides.

Thirteen classic modes

  • Team dead match and Last man standing, with a play area that shrinks as the match goes on.
  • Capture the flag. Steal the other team's flags and bring ten of them home.
  • Zombie survival. Both teams against the zombies. Hide in houses until the doors give way.
  • Zombie vs player. One team is human, the other fights with claws and heals with every hit.
  • Explosive battle and Abyss Clash. Grenades and molotovs only; Abyss Clash adds pits to fall into.
  • Sniper duel, Sword duel, Knife fight and Hand to hand combat. One kind of weapon, no excuses.
  • Snowflake survival. Collect snowflake shards and throw them. One freeze is fatal.
  • Collector's arena. No fighting: collect the most gold in ten minutes.

Most of them can be played in teams or everyone for themselves.

Freedom fight: the city of Brackenford

Freedom fight needs no match. A helicopter flies you over the city, you choose where to jump, open your parachute and land in a fight that is always running.

A city you can learn by ear

Brackenford is 600 by 600 steps: Meridian Plaza with its fountain, the three-storey Halcyon Arcade, the Thornwood forest, the Silverrun Canal with five bridges, the Ironmill Works, a hospital, a school, a hotel tower and a farm. About 60 buildings can be entered, and every room sounds like its size.

Stairs, roofs and the Underline

Real stairs lead to upper floors and roofs, ladders to the water tower and the bell tower. Under Lantern Avenue runs the Underline, a railway tunnel with three stations.

Windows that break

735 glass windows. Shoot one, or put a grenade through it, and it becomes an opening you can fire, climb and listen through. The glass on the floor crunches under whoever steps in next.

Events all day

Supply airdrops in three tiers, red zone bombardments with a warning and a way out, eight control points to capture and hold, helicopter extractions, and supply stations along the streets. Every announcement tells you the direction and the distance from where you stand.

Loot and shops

About 220 chests in houses, cellars, warehouses and the metro. Tanner's Market holds the seven shops. A compass and a guide beacon lead you to any place you pick.

Never an empty city

When few players are around, computer-controlled fighters drop in by helicopter. They loot, take cover, reload, hold control points and can be beaten like anyone else.

Weapons

Rifles such as the M4, the AK-47, the MKEK MPT-76 and the M1 Garand. The Tayfun light machine gun with its 60 round belt. Shotguns, pistols, a revolver and the GSG-5. Sniper rifles with a scope. Knives and swords you can also throw. Hand grenades, smoke grenades, molotovs, mines, time bombs and remote charges.

Vehicles

Motors carry a driver and passengers. They have gears, a horn you choose, locks, a dashboard on H, nitro that you earn by driving, and damage that you hear in the engine. Ram an enemy, crash into a wall, or have your parked motor stolen. Bikes have three gears and their own health. Sprint trials keep personal bests and a top ten.

Characters with their own voices

Your character is your voice in the fight: pain, a death cry, lines for your kills. Tristan comes with every account; Aria, Kade, Razeon, Shadow, Hex, Supreme and Lord can be added. A character is a voice and an identity. Every character has the same health, speed, jump and damage.

An arena announcer calls the big moments: first blood, double kill, rampage, shutdown, victory.

Hear a sample (11 seconds, nothing plays until you press play):

Knocked down, and lifted back up

In freedom fight, team dead match, last man standing and team deathmatch, a lethal hit knocks you down half of the time instead of killing you. You lie where you fell, you can still talk, and your character groans so that helpers, and enemies, can find you. A team mate or a friend stands next to you, presses T and stays close for four seconds, and you are back on your feet. If nobody comes, it ends.

Items

Bandages and med kits. An ammo box that fits whatever you hold. Decoys that fire fake shots, a lure that walks fake footsteps away from you, motion sensors and trip wires. Smoke that hides you from lists and scopes. Shields, a helmet, barricades, ladders, binoculars, a jammer, and a supply flare that calls a helicopter to your position and tells the whole map about it.

Groups, bases and friends

Found a group in freedom fight and it gets a base with chests for its members, a door with a password and up to four more bases later. Bases can be attacked, so defend them. Communities give you a shared chat and a voice channel without a base. Friends, a watchlist, profiles, polls and an activity feed keep you in touch.

Missions and progression

Voice chat

Press V and the players near you hear your voice from where your character stands. Press B to talk to your whole community, wherever its members are. Push to talk or a toggle, your choice, and you can set the volume of every speaker.

Languages

Chat channels for 27 languages, from Turkish, English, Spanish and Portuguese to Arabic, Persian, Hindi, Indonesian and Vietnamese. Messages can be translated as you send or read them. Players have also translated the game's own texts into many languages, and you can pick one of those translations in the game.

What's new

Straight from the game's own list of changes, newest first. Open an entry to read it.

New in 11/10/2026: the same gestures on Android and iPhone (coming with the next version of the game).
  • NEW: Triple tap with 2 fingers at the top centre, the middle or the bottom centre of the screen copies the last spoken text to the clipboard, on Android and on iPhone and iPad, in the game and in the menus.
  • FIXED: Android, iPhone and iPad: double tap with 2 fingers in the middle (community voice chat) no longer switches the microphone at the second tap, so a triple tap there does not turn it on or off.
  • FIXED: Windows: F10 copies the last spoken text in the menus too, not only in the game.
  • NEW: Android: triple tap with 3 fingers quotes the selected message, as on iPhone and iPad.
  • NEW: Android: "view packs you bought and open them" is in the action menu, as on iPhone and iPad.
  • CHANGED: iPhone and iPad: jumping 5 items in a menu with a 2 finger swipe up or down now goes round from the end to the start when menu wrapping is on, as on Android.
  • The only gesture difference left between Android and iPhone is the back gesture: on iPhone and iPad a tap in the top left corner goes back, so the gestures that use the top left corner there are done with 2 fingers, and switching to punch is a 2 finger tap in the top right corner.
New in 09/10/2026: switching accounts, for real this time.
  • FIXED: Switching to your other account with Shift+P (or Switch account on the phone) could still drop you at the sign-in options. The server told your game that your old character had gone offline just before it sent the new account, and the game took that as being signed out. The server no longer sends that message to the player who is switching. This works with the game you have now, on every device; there is nothing to update.
New in 08/10/2026: built-in voice settings for iPhone and iPad (coming with the next iPhone version).
  • These changes are for iPhone and iPad only, and they arrive with the next iPhone and iPad version of the game (2.0.1), as soon as the App Store approves it. They are not in the Windows or Android versions.
  • NEW: In the settings there is "Built-in voice speed". It sets how fast the game's own voice talks when the screen reader is not speaking for the game, for example when VoiceOver is off. Each tap moves to the next speed, from very slow to fastest, and you hear the new speed at once.
  • NEW: In the settings there is "Built-in voice". It lists every voice installed on your device, English voices first. Choosing a voice says a short sample in it and keeps the list open, so you can try several. "System default voice" goes back to the voice your device uses. Voices you download in the iOS settings appear in this list too.
  • NEW: In the settings there is "Enable menu wrapping", like on Android. Turned on, every menu wraps around: swiping up on the first item takes you to the last one, and swiping down on the last item takes you back to the first. Turned off, which is the default, menus behave as before.
  • NEW: In the settings there is "Enable drawing weapons into the right hand", like on Android. Turned on, the weapon you choose by swiping left or right at the top of the screen goes into your right hand instead of the left.
  • NEW: In the settings there is "Disable speaking of typed characters", like on Android. Turned off, the game no longer says each letter you type or delete in a text box while VoiceOver is off. With VoiceOver on, deleted letters are still said, because VoiceOver cannot read them in the game's text box.
  • FIXED: The game's own voice no longer stops speaking when you touch the screen, so a message is not cut off when you start a gesture.
  • FIXED: In the speech history, choosing a line now says "Copied to the clipboard." The line was copied before too, but nothing was said, so it seemed that nothing happened.
  • FIXED: With the game in Arabic or Russian and the iPhone set to another language (for example German), the game's own voice said nothing, because iOS uses the voice of the phone's language and that voice cannot read Arabic or Russian letters. Now, unless you choose a voice yourself, such text is read by an Arabic or Russian voice of your device.
New in 06/10/2026: no more long freezes after timed actions.
  • FIXED: Putting on or taking off a helmet, the silencer, the ladder and other short timed actions could keep you frozen for much longer than they take (10 seconds or more) when your connection was losing packets. The game now lets you move again on its own once the action is over, even if the server's "go" message is late. You need the new version of the game for this fix.
New in 05/10/2026: switching accounts.
  • FIXED: Switching to your other account with Shift+P in the lobby works again. Before, picking the other account could drop you back at the sign-in options with your old account and nothing said. You need the new version of the game for this fix.
New in 04/10/2026: the Kel-Tec P318.
  • CHANGED: The Kel-Tec P318 is back as a weekly weapon. Each copy lasts one week from the first time you draw it, and another copy adds a week to the time you have left. It is now the strongest pistol by range, accuracy, fire rate and its 20-round magazine, but it takes 4 or 5 body hits to take someone down. It is sold in the web shop at audiowander.com/zero-shop for GBP 5 a week.
New in 03/10/2026: shops and motors.
  • FIXED: Players whose connection dropped about half a minute after logging in, on some mobile networks (for example Jio) and through VPNs, should now stay connected. The server sent its data in packets too big for those networks, so the large ones were lost on the way while the small ones still arrived; the server now sends smaller packets to everyone.
  • The e-mail question at login now says what is wrong with your saved address, for example that it ends with an extra period, has a space, looks mistyped (gmail.co) or does not exist, and suggests the corrected address when it can.
  • FIXED: Entering the freedom fight map no longer floods slower computers. A few seconds after you arrive, the game re-sends about 500 changed map pieces (chests, windows, base entrances) so your copy of the map is correct; this used to come all at once and could freeze a slower computer until the connection dropped. It now comes spread over a few seconds.
  • FIXED: Buying in the Brackenford shops works again from the shop door and anywhere near the counter. The shops opened there this morning, but the purchase itself still wanted the exact counter square and said you can only buy this at the shop.
  • FIXED: The game no longer stays on the loading screen at start when the message of the day cannot be fetched (a blocked or very slow network). It waits at most 8 seconds and then goes on to the main menu.
  • FIXED: Every shop in Brackenford now opens with Shift+Enter (on Android, triple tap the middle of the screen) anywhere at its booth and in the 4 squares around it, including the shop door the zone tracker leads you to. Before, only one exact square inside worked. Trying to buy a motor in the lobby now tells you where motors are sold: in the vehicles category of the store once your match has started, or in freedom fight at the vehicle shop Axle and Spoke in Tanner's Market.
New in 02/10/2026: easier sign up and login on weak connections, and 500 players at once.
  • FIXED: Choosing Arabic (or another big language) no longer freezes the game. The language file (1.3 MB for Arabic) was split word by word when it arrived, which froze a phone for many seconds and could drop the connection; the game now reads only its first words. Translating new messages is also about five to nine times faster. The server no longer sends the same language file again at the next login after you chose it in the menu.
  • FIXED: If the code never arrived because the e-mail address of an account does not exist (for example a typing mistake, or an address ending in gmail.co instead of gmail.com), the server now notices that the mail came back. A new account is told so at login: type your correct address in the e-mail field and the code goes there. An older account is let in and asked for a working address in the game. Registration also catches gmail.co and similar typos and asks: did you mean gmail.com?
  • FIXED: On the Windows server some players' game froze at every step. Where the server's picture of the map and the player's did not agree, the new wall check refused every step and sent the player back, hundreds of times a second. The server now notices this, takes the player's own position and pauses the check for that player for 30 seconds.
  • FIXED: Password recovery and login no longer refuse your e-mail address because of capital letters or spaces (phone keyboards often write the first letter as a capital, and the game then said "The Email is not correct").
  • FIXED: "Your device could not be identified" at login on Android. An e-mail address saved with a space at the end (phone keyboards add one after a suggested word) moved the device code out of its place in the login. The server now reads it correctly, and the game removes such spaces (the space part comes with the new game version).
  • FIXED: Some players froze in front of group base entrances and chests in freedom fight, mostly on phones. On a slow line these objects could arrive before the map itself, and loading the map then removed them on the player's side, while the server still had them, so every step there was refused. The server now sends them once more 3 seconds after a map is loaded.
  • IMPROVED: Verification codes are now numbers only. Phone keyboards sometimes "corrected" the old letter codes into words, and the code was refused. A code typed with a space in it is also accepted now.
  • FIXED: Players who play in a big language (Arabic above all) were disconnected about 10 seconds after every login: the game sent the whole language file (1.3 MB for Arabic) at every login, and on a slower connection it never arrived. The file is now sent only when it has changed, and only after you have been in the game for 20 seconds.
  • IMPROVED: Each server now takes up to 500 connections at the same time.
  • IMPROVED: Older versions of the game that do not send a device code can log in again. They confirm the device once with the e-mail code, like everybody else.
  • IMPROVED: Creating an account tries to reach the server three times instead of once. If it still cannot, the game says what to check (your internet connection, a VPN or proxy) instead of "Server lost". This comes with the new game version.
  • IMPROVED: Logging in says the same after the third failed try. This comes with the new game version.
  • IMPROVED: On phones, setting up an existing account, creating an account, recovering your password and typing the verification code now use the phone's own text field, which TalkBack and VoiceOver handle like any other text field, with OK and Cancel buttons. The game says the question before the field opens, also without a screen reader. This comes with the new game version.
  • FIXED: On Android the first download of the game sounds could stop at about 10 percent on a slow but working connection: each 8 MB piece had to arrive within two minutes or it was thrown away. Now a piece is only given up when no data comes for 45 seconds, and after a problem the game continues in smaller pieces. This comes with the new game version.
  • FIXED: On phones, Enter in a text box sometimes added a new line instead of confirming, for example after a name that starts with a capital letter (phone keyboards report Shift with capital letters). On phones Enter now always confirms. This comes with the new game version.
  • IMPROVED: On Android, the message that asks you to suspend TalkBack now also says that you turn TalkBack on again to type in a text box (for example your username or a verification code) and off again afterwards. In English, Arabic, Spanish, Portuguese and Turkish.
  • FIXED: On phones, the Enter key of the on-screen keyboard now confirms a text box, for example the verification code. Some keyboards sent it as a new line and nothing happened. This comes with the new game version.
  • FIXED: On phones the game is paused while you read the e-mail with your verification code, and the server then dropped the connection, so the code you typed was lost ("Connection lost"). The game now reconnects by itself and sends the code you typed; you are not asked again. The code stays valid for 15 minutes. This comes with the new game version.
  • FIXED: Account creation stopped at the first wrong field and no longer goes on to the server with it, and it no longer waits for ever when the server does not answer. This comes with the new game version.
New in 01/10/2026 (tenth update of the day): one-time e-mail check for every account.
  • NEW: Every account confirms its e-mail address once. At your next login the game mails you a code and asks for it, even on the phone or computer you always use. After that you log in exactly as before, and only a new device is asked for a code.
New in 01/10/2026 (ninth update of the day): fair play against alt accounts, walls and falls checked by the server, and many small fixes.
  • IMPROVED: Zero tokens cannot be transferred or gifted to an account on the same device or the same internet connection.
  • IMPROVED: Group bank: the owner of a group cannot take out the zero tokens that another of his accounts on the same device or connection donated. They stay in the group bank. Everybody else's donations work as before.
  • IMPROVED: Items dropped by an account cannot be picked up by another account on the same device. Everybody else can pick them up as before.
  • IMPROVED: Items that an account put in a chest, also in a group base chest, cannot be taken by another account on the same device.
  • IMPROVED: The corpse of an account and the weapon it dropped when it died cannot be looted by another account on the same device.
  • IMPROVED: Killing another account on the same device gives no zero tokens, no score points and no XP, and counts for no missions.
  • NEW: If two players really share one device or one internet connection, for example brothers and sisters at home, the staff can allow it for their two accounts. Write a ticket.
  • FIXED: Nobody can walk through walls any more, also not with a modified game. Nobody can fly over walls or drop through the floor either.
  • FIXED: A hard landing always hurts, also when a modified game hides it. For the normal game nothing changes: the same falls hurt as much as before, and an open parachute still protects you.
  • FIXED: Renaming your character no longer moves an ignore, a staff permission or a purchase of the old name to a new player who later takes that name.
  • FIXED: Store purchases stay with your account after you rename your character.
  • FIXED: You can rename your character to the same name with accents.
  • FIXED: Players who finished a match could not rename or delete their account ("Leave your match first."). This works again.
  • FIXED: Weapon information speaks its old sentences again.
  • FIXED: A motor with several riders no longer takes the grenade blast once for every rider.
  • FIXED: A purchase that belongs to another account is no longer checked again every minute.
  • FIXED: Players who share an internet connection can poison each other with a poisoned blade like everybody else.
New in 01/10/2026 (eighth update of the day): the freedom fight helicopter is heard over the whole city, drop zones in every district, fairer zero token transfers, faster ranking lists and several cheats closed. A few changes come with the new game version and are marked so.
  • FIXED: In the freedom fight helicopter, the helicopter's sound faded away as soon as it flew past 500 steps east or north, and you heard a fall and "unknown area". The helicopter now sounds the same over the whole city of Brackenford.
  • IMPROVED: Freedom fight helicopter: you can now choose a drop zone in every district of the city, as well as the control points, the four landing grounds at the edge of the city and a random spot.
  • FIXED: If a player ever stands outside the edge of the freedom fight map, he is put back on free ground in the city.
  • IMPROVED: Less network traffic while a match starts in the helicopter. Other players now hear your helicopter steps only when they are near you, as in freedom fight.
  • FIXED: Closed several ways a modified game could cheat with items, weapons, bombs, shops and chests. Nothing changes for players of the real game.
  • FIXED: The shops of the freedom fight map sell only at their counters again.
  • FIXED: Each boom box and each adrenaline shot works only once.
  • FIXED: Tickets can only be read and answered by the player who created them and by the staff.
  • FIXED: Private matches can only be joined with the password or an invitation. Only the creator of a match can kick, ban or invite players, and only players of that match can be kicked or banned.
  • FIXED: Chat messages and private messages are always one line, so nobody can make a message look like a server message.
  • IMPROVED: The link filter finds more ways of writing a link.
  • IMPROVED: A new name that would sound like an existing one (the same name with accents or with look-alike letters from another alphabet) is refused, so nobody can pretend to be another player or a staff member.
  • IMPROVED: You can send 3 suggestions and 12 ticket messages every 10 minutes.
  • IMPROVED: Transfer zero token, in the player menu: you can transfer up to 200 zero tokens a day, and never to an account on the same device or the same internet connection. Gifts to friends already had a daily limit.
  • IMPROVED: You can create three accounts per e-mail address. For Gmail addresses, dots and anything after a plus sign count as the same address.
  • IMPROVED: The ranking list in the main menu, "view scoreboard" in the game menu and "view current event scoreboard" in the events menu now open at once. Opening them used to make the game lag for every player for a moment.
  • IMPROVED: The ranking lists show the newest score and event points of the players who are online. Before, they showed what was last saved.
  • IMPROVED: Creating a new account no longer makes the game lag for the players who are online.
  • FIXED: In the new game version, the game no longer waits for ever at "Logging in ..." when the server does not answer. After 30 seconds without an answer it tells you "The server did not respond. Please try again later." and you are back in the Login Options menu.
  • FIXED: In the new game version, if the connection is lost while you are logging in, the game tells you "Connection lost from the server." and goes back to the Login Options menu instead of waiting.
  • FIXED: In the new game version, after a login that did not work (for example a wrong password), the next try while the server is offline says again that the server is not active and keeps trying. Before, it could wait at "connecting to the server" for ever.
  • IMPROVED: The new messages of this update are translated into Arabic, Spanish, Portuguese and Turkish.
  • IMPROVED: The game readme has the new drop zones, the login messages, the transfer rules and "Switch account" in the action menu on phones.
New in 01/10/2026 (seventh update of the day): switching between your accounts with Shift+P works every time, also when you switch quickly.
  • FIXED: Switching back quickly to an account you had just left with Shift+P could leave the game at "Logging in" for ever. You now get into your account, and if it really cannot leave the game yet you are told why and can try again.
  • FIXED: When you switch accounts with Shift+P, your old character now leaves the game and is saved right away. Before, it could stay standing in the game for up to half a minute after the switch.
  • FIXED: Pressing Shift+P again soon after a switch said "Please wait a moment and try again." The list of your accounts now opens at once. Pressing Shift+P twice by mistake opens it only once.
  • FIXED: While you are knocked down, Shift+P now always tells you "You cannot switch accounts while you are knocked down." Before, it often said nothing.
  • IMPROVED: With a time bomb nearby you cannot switch accounts, and Shift+P tells you so. Before, the switch went ahead while your old character had to stay at the bomb.
  • FIXED: After a lost connection beside a time bomb, the next player who connected could get stuck on the way into the game. This no longer happens.
  • IMPROVED: The list of your accounts is in alphabetical order.

The complete list of changes, back to 2023, can be read in the game.

Store

Zero Tokens are the game's currency. You earn them by playing: kills in matches, finished matches, missions, control points, extractions and level rewards. You spend them in the in-game store on weapons, ammunition, equipment, potions, vehicles and characters.

Zero Tokens

Short on time? The web shop offers Zero Tokens that are added to your account. They buy the same things as the tokens you earn in play, at the same prices.

Paid account

A way to support the game and get some comfort in return: a kill line and last words of your own, a supporter tag, an About me text on your profile, more sound emotes and horn sounds, a longer watchlist and combat log, an extra mission reroll, a weekly cosmetic reward and the premium cosmetic track of the Season Pass.

Fair play

No purchase raises your damage or your health. Everything that matters in a fight can be earned by playing, and every character has the same strength. The new match modes hand everyone the same equipment.

Questions and answers

Is the game really free?

Yes. You can download it, create an account and play every mode without paying. The currency of the store is earned by playing.

Can I buy an advantage?

No purchase raises your damage or your health, and every character has the same strength. Paying saves time and adds comfort and cosmetics. A player who never pays can earn everything that matters in a fight.

Do I need a screen reader?

The game speaks through your screen reader when one is running, and through built-in speech when not. On Android, iPhone and iPad it works with touch gestures.

Do Windows and mobile players play together?

No, and that is on purpose. Windows players have a keyboard, while many phone players play with touch only, so mixing them would put phone players at a disadvantage. Windows has its own server, and Android, iPhone and iPad share another one. If a phone player wants to face Windows players anyway, they can choose the Windows server with "choose server" in the main menu. The Windows game has no server choice, so the mobile server stays a fair place for touch players. That is why this page shows two player lists and two sets of scoreboards.

Can I play when nobody else is online?

Yes. Matches can be filled with computer-controlled fighters, and the freedom fight city has fighters of its own when it would otherwise be empty. Rewards and records that count against other players still need real opponents.

What do I need to play?

A Windows computer, an Android phone or tablet, or an iPhone or iPad, an internet connection, and stereo headphones. A microphone if you want to use voice chat.

When can I download it?

The download buttons are at the top of this page and in the download section. Platforms that still say coming soon will follow.

Where can I read the privacy policy, or delete my account?

The privacy policy of Zero Hour Assault is on this site. Account deletion is described on the account deletion page.
