Trooper VS Zombies is a fantastic free online game. This is a bit bloodthirsty but cool action game. First, you get a weapon from a dealer: a rifle, a grenade launcher, a machete, or a knife, and then you go in search of zombies. There are checkpoints, and you know in advance how many zombies you need to kill on them to complete the level! Brass knuckles are your first weapon, test yourself on a midnight street full of zombies!
