Take part in a 2D battle unblocked game called Biters IO! There are no weapons except your powerful jaws. Feed your character cookies with chocolate to grow a monster that can eat any player on the server! Growth adds power to your teeth and increases the warrior in size, which gives more damage to the bite.
Nevertheless, at first you should still come up with an awesome nickname for your opponents, and only then go to the map, where everyone is already eager for a fight with your hero. You have enough mouse to feed your little warrior with cookies and fight with the enemies. Try not to die, good luck in the fight!
