The third downloadable content pack for Call of Duty: Black Ops, Annihilation, has received a brand new video, a few more details about the maps included, as well as a list of the achievements that are enabled in the new Zombies experience.

Call of Duty: Black Ops is still one of the most played games online, despite being released last year, so Treyarch and Activision, its developer and publisher, are continuing to release new content in order to keep players hooked on the experience.

We've already seen two downloadable map packs be deployed for the game across three platforms, the PC, PlayStation 3 and Xbox 360, in the form of the First Strike and Escalation DLCs.

Now, the two companies are getting ready to deploy the Annihilation map pack for Call of Duty: Black Ops next week, exclusively on the Xbox 360 console.

We've seen a few details appear about the four new competitive multiplayer maps, as well as the new cooperative Zombies scenario, alongside a video, but Treyarch has now released some new information about them.

Check out the official descriptions of the new multiplayer and cooperative maps below.

"Take the fight to "Hangar 18," located in the iconic military base Area 51, complete with experimental weapons labs, the SR-71 test hangar, and a disturbingly mysterious autopsy room. Pull up and get cozy with "Drive-In," a close quarters slugfest through a 60's American drive-in theater, classic arcade, and old school snack shack. Battle through the construction of a massive secret Soviet missile site in the multilevel "Silo," and then take off to a coastal golf course fit for a dictator in "Hazard," set on the cliffs of Cuba where stocked clubhouses and manicured fairways meet sand traps perfect for setting up ambushes."

"Zombies return with vengeance in the mysterious land of "Shangri-La," a legendary shrine lost in an exotic jungle. Never before seen undead creatures lurk within a treacherous labyrinth of underground caverns. Step carefully through deadly traps and solve the dark secrets buried within the shifting walls of a long last land."

The development studio also detailed the new achievements that can be unlocked when playing the Shangi-La Zombies map, totaling 150 new achievement points.

Time Travel Will Tell (75G) – In Shangri-La, acquire the focusing stone. Blinded By the Fright (30G) – In Shangri-La, kill a Shrieker zombie while blinded by it. Zomb Disposal (30G) – In Shangri-La, dispose of a Napalm zombie without it harming any players. Monkey See, Monkey Don't (5G) – In Shangri-La, get something from the monkeys. Small Consolation (10G) – In Shangri-La, use the 31-79 JGb215 on each type of zombie.
