I had no idea zombie Hilter was missing. Zombie Army Trilogy is heading to Xbox One in its total undead glory.

Sniper Elite's spin-off zombie game, Zombie Army is being remastered with brand new content.

Aside from being completely remastered there's a new horde mode, 10 new levels and more new playable characters.

Zombie Army Trilogy is due out later this year on Xbox One, PS4 and PC.
