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.
Shoot the enemies with a pistol or a sniper rifle. Don't let any get away as you move to
new levels. Mouse to aim and shoot. 1-3 switch weapon and R to reload.
