Dead East: Patient Zero 1918

If Inglourious Basterds and Overlord spawned a savage, adrenaline-fueled lovechild, DEAD EAST: Patient Zero is that bastard.

Forged in the meat grinder of war, a horrific plague erupts from the trenches of mire and blood, where enemy soldiers not only fight each other through the choking mustard gas chaos, but also against an army of the undead.
