Braains.io

Braains.io is an infection-survival arena where one player starts as a zombie and the rest are humans. The zombie infects on contact, converting humans into zombies. The round ends when everyone's a zombie or the timer runs out — surviving humans win.

How to play

WASD to move. Humans can sprint briefly, jump platforms, and use map verticality to escape. Zombies are faster but can't reach high spots without jump assists. The longer the round, the more zombies on the field — late-game is pure chase.

Tips

As human: stay high, climb early, don't get cornered
As zombie: predict human routes; ambush near choke points
Group survival doesn't help — humans clustered die together
The zombie speed boost means rooftops eventually become unsafe — keep moving
