Zombie Army Trilogy

Experience gut-wrenching third-person horror and intense co-op action from the creators of Sniper Elite 3.

Defeat harrowing legions of flaming zombies, armoured skeletons, undead snipers, fire demons, chainsaw-wielding elites ... and worse ... before facing the demonic Führer himself.

Finally, face your fears in the ultimate test: a brutal Horde Mode for 1-4 players across 5 blood-curdling maps. 3D display with compatible 3D active glasses (sold separa
