Activision has released yet another trailer for the 'Annihilation Map Pack' DLC for Call of Duty: Black Ops. Set to launch on the Xbox 360 tomorrow, this trailer focuses on the new zombie level.

Though a release date for the PC and PS3 version of the game's third DLC pack has not been announced, if it follows the pattern set by the last two packs, it will launch roughly one month after tomorrow's Xbox Live debut.
