A listing appeared briefly on the official Call of Duty forums for a Call of Duty Black Ops: Zombies app on Android, possibly outing a release that has yet to be officially announced.

CoD: Zombies first appeared in Treyarch's Call of Duty: World at War, where it earned the nickname "Nazi Zombies." It's since appeared again in Call of Duty: Black Ops and as a standalone game on Apple iOS devices, and it's expected to return in Call of Duty: Black Ops 2 later this year.

XperiaGamer took some screenshots, which show that the removed post was a "field manual" for the Android version of the game, which will feature "a fully replicated Kino der Toten and 50 levels of the cult-favorite Dead Ops Arcade."

Have you been waiting for CoD: Zombies on Android? Do you think Activision will announce it soon? Tell us in the comments or on Twitter.
