Tribulation is a shooter game, where the aim is to eliminate zombies one after the other to make sure they don’t get the better of you and eat you up! Survive for long enough to earn experience and level up. Spend points on a skill tree to upgrade your character and buy new, more powerful weapons at the shop. Once your rage bar is full, consume it all to activate fury mode and do some serious damage!
