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

Scoreboards

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 14/11/2026: Connecting to the server (coming with the next version of the game).
  • FIXED: When the server cannot be reached, the game now says "connecting to the server, please wait..." again each time it tries to connect, so you know a new attempt has started.
New in 13/11/2026: Season pass, tickets and first steps.
  • FIXED: Buying the season supporter pass early in a new season no longer loses the unclaimed supporter rewards of the season before. They are added the next time you play.
  • FIXED: A ticket rating that ends with "ticket not found" no longer counts as your rating.
  • FIXED: Only the support team closes and reopens support tickets, as the ticket messages say.
  • FIXED: The First steps menu no longer promises an XP boost card while you already hold 50 cards.
New in 13/11/2026: Fights, watching and messages.
  • FIXED: Molotov fire now burns bots and zombies in matches, not only players.
  • FIXED: When the fighter you watch leaves, you now move on to a fighter who is still in the match instead of hearing a name that has gone offline again and again.
  • FIXED: A fainted, knocked down or dead player can no longer wake team mates with the T key; this works the same as the phone gesture.
  • FIXED: On phones, opening a corpse or a chest now explains the swipes instead of the keyboard keys.
  • FIXED: A looking for group post with a private profile is now refused with an explanation; before, the game said it was on the board, but nobody could see it.
  • FIXED: Finishing your first steps while you already hold the most XP boost cards no longer promises a card that is not added.
New in 13/11/2026: Password recovery message (coming with the next version of the game).
  • FIXED: After "Recover your password" the game now says that a new password was mailed to you, and that your old password keeps working until you log in with the new one within 3 days.
New in 13/11/2026: Matches, rewards and friends.
  • FIXED: Cancelling an Explosive battle or Collector's arena match now clears its match map, as a normal match end does.
  • FIXED: Earning an XP boost card no longer removes bought cards when you hold more than 50.
  • FIXED: A supporter pass sent to an account whose paid time ran out while it was offline now gives the pass instead of zero tokens.
  • FIXED: A player who ignores you no longer hears your name when you commend them; the commendation still counts.
  • FIXED: When you already have 3 friend requests waiting, the menu now comes back after the message.
New in 12/11/2026: Game fixes.
  • FIXED: In Gun game, only a real knife kill wins at the knife level; a fighter whose name contains the word knife no longer wins with another weapon.
  • FIXED: Bots no longer pick up boom boxes, so the trap stays where you put it.
  • FIXED: A weapon melee hit now starts the one minute wait before the victim can leave the freedom fight map, like shots and punches.
  • FIXED: Picking up a small or vitality potion plays one pickup sound instead of two.
  • FIXED: A gift message no longer reaches a friend who ignores you; the gift tokens still arrive.
New in 12/11/2026: Settings menu in other languages (coming with the next version of the game).
  • FIXED: When the game runs in another language, a setting line now changes between enable and disable as soon as you switch it, instead of keeping the old word until you open the menu again.
New in 12/11/2026: Fixes on the server.
  • FIXED: In Zombie vs player, zombies can no longer draw the match gun or knife; they fight with their claws only.
  • FIXED: A bot woken from a faint in Team dead match or Zombie vs player now counts for its team for the whole time it can be woken.
  • FIXED: The spatial amplifier blast no longer reaches players in the jail, the helicopter, Collector's arena, Abyss clash or Explosive battle.
  • FIXED: Placing a spatial amplifier now finds a player within 5 tiles even when a player you already tagged stands next to them.
  • FIXED: The descriptions of the daily events "survive for 10 minutes" and "make 50 headshots" now say how their event points really work.
  • FIXED: New polls, votes and poll comments are no longer announced to players who ignore that person.
  • FIXED: Removing a friend from the player menu while they log out now removes you from their friend list too.
  • FIXED: The weapon guide now says 5 body hits for the Kel Tec P3 18.
  • FIXED: The weapon of the day now changes on the same day as its daily notice and its daily bonus count.
  • FIXED: The match list on the website counts real players only, not bots.
New in 12/11/2026: Fixes in the game app (coming with the next version of the game).
  • FIXED: In Zombie vs player, the inventory menu no longer draws a weapon for a zombie.
  • FIXED: Opening "View ranking list" again too quickly now says "Please wait a moment and try again." instead of waiting in silence.
  • FIXED: On Windows, a closed support ticket now always offers "rate the ticket" when it still needs a rating, also after it was reopened and closed again, so you can open new tickets.
New in 12/11/2026: Matches, rewards and menus.
  • FIXED: After a classic match ends, its rules no longer follow you: no more fainting instead of dying in a group base, and no snowflake shards outside the match.
  • FIXED: A match creator can no longer kick or ban a player who has already left the match.
  • FIXED: Knives and swords can no longer be thrown in jail, in the helicopter, in Collector's arena, Abyss clash or Explosive battle, where firing is not allowed either.
  • FIXED: Battle royale and the round modes: a player who is already out and logs in again on the arena is now sent off the arena instead of fighting on.

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.

How to start

  1. Install the game for your platform from the download section. Updates of the game and its sounds are downloaded by the game itself.
  2. Create an account from the game's main menu: a name, a password and an e-mail address that you can reach. The e-mail address is how you get back in if you ever lose your password or change your device.
  3. Put on headphones. Everything in the game is placed around you in sound: left, right, in front, behind, above and below.
  4. Walk around the lobby, open the game menu with O and read the guides there. The game menu also holds the rules of every match mode.
  5. Play. Join or create a match from the lobby, or take the helicopter into freedom fight.

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.
