What would you do if the zombie apocalypse came? Don't rely on movies and other information, people should defend their homes. Grab a grenade launcher and try to blow every single target you see. Show the no mercy and blow them up!
There is no other profession for you at the zombie apocalypse, but the zombie hunter. Defend those who is still not infected from the hordes of hungry zombies. Clear the levels one by one and launch bombs straight to the zombies or the spiky wheels that will kill them after the explosion. You have a limited amount of bombs, so aim carefully before you shoot!
