It's a nightmare. You are trapped in an abandoned mine with an injured comrade at your side against God-knows-what. Make your stand, get out alive. Three words of advice: shoot to kill. These things are not human, they are monsters..
Zombies have attacked and mankind has been devastated. Every day is a battle in the war to survive. Few remain to hold them off. Shoot those zombies and save the world.
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.
As you fight hordes of undead demons exploring the Death Wizard's mysterious castle, you'll find spells that will allow you to use the elemental forces. Good luck!
