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.
A top-down shooter with over 25 weapons and 50 levels. These zombies are faster and more aggressive than usual. Choose your hero and shoot down those brain dead fools.
