Activision has released a new, multiplayer trailer for its best-selling shooter Call of Duty: Black Ops. The 'Annihilation Map Pack' is set to launch on the Xbox 360 on June 28 and includes five maps: four competitive multiplayer arenas and one Zombie-mode specific locale.

Though a release date for the PC and PS3 version of the game's third DLC pack has not been announced, it will presumably follow the same schedule as past add-ons. The two previous downloadable content packs launched roughly one month after it debuted on the Xbox Live Marketplace.
