Zombain .io is another fun-addicting multiplayer online shooting IO game about bloodthirsty zombies. Enter a field packed with evil undead creatures and other players and try to kill who or whatever steps too close to you. Everything that moves will try to kill you, so show no mercy and shoot the crap out of everyone. Collect cool power-ups, like the machine gun, the shotgun or the health kit, and lots of those donut looking items scattered all over the field to level up and unlock new skins. Have fun with Zombain IO!
