A great combination of zombie shooting and 'match-three' puzzling with an atmospheric (and bloody!) horror theme. Match up and pop the monster heads before they reach the barricade. Use grenades to get out of a tight spot.
Another Doom style game called "Flatten Horizon" with top view game play. Plenty of monsters, weapons, blood and doom like action in different perspective.
An unknown virus plagued the planet, bringing all sorts of monstrosities, ranging from zombies to flying beasts. Enter this apocalyptic world and try to survive as long as possible.
