Braains.io

Braains.io is a wildly fun multiplayer zombie survival game that pits humans against zombies in a frantic game of “tag” with a twist. In each round, you’ll either be a quick-thinking human scrambling to survive, or a hungry zombie determined to infect everyone. Every match starts with most players as human and one player (chosen at random or by choice) as the initial zombie – and with up to 50 players in a server, the chaos is off the charts! Humans must run, hide, and strategize to avoid becoming zombie chow, while the zombie team chases them down to spread the infection. It’s a hilarious, fast-paced showdown that can turn friends into enemies in a heartbeat, keeping you on your toes and laughing all the way.

Survive, Hide, and Team Up (Human Gameplay)

As a human in Braains.io, your goal is simple: stay alive until the round ends without getting tagged by a zombie. Of course, that’s easier said than done when ravenous zombies are on your tail! You’ll need to get creative and work together with other survivors. Barricade yourselves inside buildings, push furniture or crates against the doors, and find clever hiding spots to wait out the undead onslaught. The game’s maps are full of houses, rooms, and even outdoor nooks where you can take cover. Hiding spots can be anywhere – inside a closet, behind a pile of boxes, or even sneaking under a tree so your character (and name tag) stay out of sight. Teamwork is key: a well-coordinated group of humans can build impromptu fortresses and hold off the horde longer by watching each other’s backs. Just be careful whom you trust... that helpful buddy beside you could turn into a zombie at any moment!

Spread the Infection (Zombie Gameplay)

If you start (or become) a zombie, get ready for a totally different kind of fun. As a member of the undead team, your mission is to hunt down every last human. Zombies don’t have fancy weapons – instead, you are the weapon! Simply rush toward a human and tag them by touch. With Braains.io’s quirky 2D physics, you can even shove aside barricades or find alternate routes to corner those pesky survivors. The moment you manage to catch a human, they instantly switch sides and join the zombie team, swelling the ranks of your undead horde. There’s nothing more satisfying (or delightfully evil) than watching a former survivor turn green and help you chase their onetime friends! Each new zombie makes the chase even more intense, as the balance shifts and the pack of zombies grows larger with every tag. Before long, a round that began with one zombie can turn into a full-on zombie swarm, with the last few humans making a desperate final stand against overwhelming odds. It’s a thrilling snowball effect that ensures no two games are ever the same, and it keeps the tension high until the very end of the round.

Playful, Fast-Paced Action

Braains.io delivers its zombie mayhem in a lighthearted, accessible style that anyone can jump into. The controls are simple – just use WASD or arrow keys to move (no complicated abilities to learn) – so you can start playing in seconds. In fact, you can hop into a match almost instantly and immediately start running, hiding, or chasing without any waiting around. Matches are short and sweet, packing a ton of excitement into each round. The game’s top-down view and charmingly minimal graphics give it a fun, cartoonish vibe (nothing too scary, just the right amount of spooky!). Don’t be fooled by the simple mechanics, though – Braains.io is easy to learn but tricky to master. Outrunning a horde of zombies or outsmarting crafty humans requires quick reflexes and clever strategy, and teamwork always makes a difference. Whether you’re plotting with friends to fortify a room or coordinating a group of zombies to ambush a hiding spot, the game rewards smart thinking and cooperation. The result is pure high-adrenaline fun that will have you yelling “Gotcha!” one minute and “Run for it!” the next.
