"This pack is really for the zombie fan. Sort of our 'season finale' really," Treyarch audio director Brian Tuey notes in the first behind-the-scenes look at the last DLC installment for Call of Duty: Black Ops.

Rezurrection (yes, it's intentionally spelled that way) is set to launch on August 23 on the Xbox 360. The DLC includes four bonus zombie maps already made available in Hardened and Elite editions of Black Ops, on both the Xbox 360 and PS3. Those users will get the fifth map, "Moon" for free. Standard edition players (including PC gamers) on the PS3 and PC will have to wait until a later date to get the content. The pack will be available for $15.
