Confused about what Zombie Army Trilogy is and what’s in it? The trailer above will walk you through the game’s campaigns, enemies, combat, explosives, and different modes.

If you’ve been following the Sniper Elite series and the Zombie Army spin-off series, the trailer will also give you a good look at some of the new enemies, environments, and improved graphics included in Zombie Army Trilogy.

If you haven’t played the Zombie Army games before, they use the same engine and gameplay from Sniper Elite V2, notably it’s ridiculously gory, slow-motion X-Ray Kill cam, but forgoes its realistic and stealthy aspects in favor of huge numbers of Nazi zombie enemies.

Zombie Army Trilogy is coming to Xbox One, PlayStation 4, and PC March 6. If you already bought Nazi Zombie Army and Nazi Zombie Army 2 on PC, Rebellion said it has no plans to release the new content included in Zombie Army Trilogy separately, but you will get a 60 percent discount on Zombie Army Trilogy automatically.
