About this app

braains.io is a multiplayer 2D pixel action game built around a zombie-marking premise. Each player joins a round as either a human survivor or a zombie, and the two sides compete on the same battlefield.

What is the goal for human players?

Humans start each round in a group with the zombies. Their objective is to evade and outsmart the zombies and survive until the end of the round without being marked. The description says humans can use obstacles or objects to block roads and stop attacks, examine the map to find hiding places, and use items in the game world to fortify their position and create safe zones.

How does playing as a zombie work?

A zombie's goal is to mark human players to spread the virus. Once a human is marked, that player turns into a zombie and begins chasing the remaining humans. As more players are converted, the number of survivors falls and the tension in the round rises. The description also suggests hunting for humans who are visible or hiding in places such as crates and corners of abandoned houses.

How do the map and barricades affect a round?

The map contains many buildings, and rubble lies at some entrances that can be used to block them. The description notes that survival chances increase when several players cooperate to block entrances. It also warns that zombies should avoid accidentally harming teammates hiding in barricaded buildings, since this can upset them. Teamwork is presented as central to success, and players are encouraged to hide in safe places with other players.

How are the controls described?

The listing says the character moves with the WASD keys and that walking up to another player marks that player. The arrow keys are also mentioned as a movement option. The description also says the game does not need attacks or fancy items. Another section, however, states that zombies attack by pressing the spacebar. Because these accounts conflict, the controls should be confirmed in the game before relying on any single input.

What is the pace and structure of a match?

The description presents braains.io as a fast-paced multiplayer game in which players choose the role of a human trying to survive or a zombie trying to infect others. The 2D environment allows players to build defenses against threats or lead a group of the undead. The listing highlights a character-switching mechanic that is meant to add surprises and keep players alert.
