Rebellion has revealed Sniper Elite: Nazi Zombie Army, which as the name suggests is an expansion to the well-received Sniper Elite V2, that introduces the obligatory undead into the fray.

Priced to launch at US$14.99 on Steam (and currently even lower with a pre-order discount), the new adventure includes a four-player cooperative campaign, and does not require the original game to function.

Featuring a co-op campaign for 1 to 4 players, Nazi Zombie Army is a horrifying new stand-alone expansion of the award-winning Sniper Elite series. In the dying flames of World War II, a despairing Hitler unleashes one final, unholy gamble – a legion of undead super soldiers that threatens to overwhelm the whole of Europe. You are Karl Fairburne – the sniper who shaped world history. You are one of the last living souls in Germany. You must team up or die. American, German, Russian – previous military allegiances no longer matter. Now it's just the living versus the dead. Only a Sniper Elite with nerves of steel and a steady aim stands a chance against Hitler’s Nazi Zombie Army!

Sniper Elite: Nazi Zombie Army is due on PC on March 1st 2013. Check out the debut trailer below.
