Cemetery Warrior 4 is a bloody action online game where you shoot demons and try to survive as long as possible. Overall, the game offers 3 modes - IMP, Demon and Satan. In all three, you will have to kill the monsters that will keep coming. The differences are mainly in receiving energy, fulfilling the life of enemies or the strength of their bosses. The game is clearly inspired by the PC game Doom, where you also fight in hell against various monsters. It is certainly not suitable for the weaker, as it also contains blood. There are really enough levels so you won't be bored.
