First teased with a trailer last month, the zombie spinoff is set in the Sniper Elite V2 universe.
The trailer shows supernatural summons, minigun-wielding zombies and four players taking on undead hordes.
Both developed and published by Rebellion, it will be released exclusively on Steam.
More details for Nazi Zombie Army will be revealed tomorrow (February 14) when it is available to pre-purchase from Steam.
A Wii U version of Sniper Elite V2 was announced earlier this month, which had been described as the most definitive version by Rebellion.
Sniper Elite V2 was released on Xbox 360, PS3 and PC last year, and received additional multiplayer content after release.
