Enter Osowiec, one of the most formidable fortresses in Europe during the Great War. It's defenders have been through hell - trench warfare, a barrage of artillery, gas - and have returned. The fortress now serves as the source of a great darkness, returning the dead to the land of the living.

You are a lone German soldier in the heat of the epic ​battle for this fortress, The Attack of the Dead Men. Your comrades have abandoned you and fled in disgrace, and now you are all alone, trapped in Osowiec, surrounded by hundreds of undead, angry Russians. Battle for survival against the hordes, and put them down once again for good to prevent the darkness from spreading over all of Europe...

There is only one path to victory - be the last man standing, dead or alive. Utilise a vast array of weapons to dispatch your foes and conquer this evil place as a one-man army. Many of the weapons in your arsenal enjoy alternate fire modes to ensure that this monumental task is executed with peak German efficiency...

The odds are truly stacked against you. Reaching the source of this great evil requires a methodical cleansing of the entire fortress complex. You will need everything you've got to deal with the increasing number of undead, who get stronger and more resilient the deeper you go...
