Braains.io is a zombie tag io game where the human team needs to avoid being infected by the infected team. Humans get infected when an infected player (zombie) touches them. The humans need to avoid the zombies by hiding and using items to block entrances like boxes or furniture. There is a timer and if the zombies infects all humans before the time limit ends then they win, but if any humans make it to the end of the time limit without getting infected they win. Every time you win as human you get bigger and faster. It is a hugely popular .io game with millions of plays.
