Braains.io

Braains.io is a highly original multiplayer survival game. You start as a living being, such as a cow, a sheep, or even a human, but you can turn into a zombie at any moment! If that happens, you can infect other players until everyone becomes a zombie.

If you choose to remain a living being, your goal is to escape zombie attacks and survive as long as possible. Hide inside different buildings, use weapons and objects to defend yourself, and block doors to make it harder for the infected to enter.

Whether you're running from zombies or joyfully spreading the infection, the game offers thrilling moments. Just join a match and start playing within seconds!

How to Play Braains.io?

Remember that Braains.io is a top-down game, meaning you can quickly see what’s happening around you. Follow our simple guide to improve your survival chances.

Playing as a Living Being or Human

• Watch the timer. The zombie wave begins after a 30-second warning.
• Find shelter. Enter a house or building, as they have limited entrances—unlike open fields, where you can be infected quickly.
• Grab weapons. The game features fun and unique weapons, each with its own advantages and disadvantages.
• Fortify your shelter. Once you’re armed and safe, start blocking entrances with furniture or any other objects to make it harder for zombies to break in.

Playing as a Zombie

• Attack in groups. Zombies are stronger when working together. If a human is well protected inside a building, call other zombies to attack simultaneously and break barriers faster.
• Anticipate human movements. Don’t run straight toward them! If they are escaping, try to predict where they’re going and block their path.
• Break obstacles. Humans often use furniture to block doors and windows. Keep pushing objects until you break through. The more zombies help, the faster barriers are destroyed.
• Be sneaky. Some players lower their guard if you don’t seem like a threat. Approach discreetly and strike at the right moment.
• Never give up. Even if time is running out, there’s still a chance to win. A single infected human can change the game by quickly turning the remaining survivors into zombies.
