Braaains.io is a free IOGame. Being a human is hard but being a zombie is harder.  Imagine what it might be like to be a zombie wandering around with a swarm of other zombies in a lonely old farmhouse as you look for foolish humans to eat. Perhaps the opposite is true, you are a human who is trying to outrun the angry hordes.  Use available weapons to kill as many zombies as possible or use your feets to run around and chomp down on as many humans as possible. The longer you survive the more points you will earn to unlock weapons that you can purchase and then upgrade. Destroying zombies is a noble pursuit just like eating humans is. This game allows you to choose who you would like to be and what you want to accomplish.
