Activision just announced Rezurrection, the fourth DLC pack for its best selling shooter Call of Duty: Black Ops. The all-zombie DLC includes remastered versions of the Call of Duty: World at War maps Nacht Der Untoten, Verruckt, Shi No Numa, and Der Riese, as well as a brand new level called Moon, which takes players to the moon to fight the zombie horde in low-G combat.

Aside from the five levels mentioned above, Rezurrection will also include a Zombies moon theme and three previously unavailable-to-purchase music tracks from the Zombies campaign. And if you’ve played the Black Ops Zombies mode thoroughly before, you’ll know that the Elena Siegman-sung songs are definitely worth the purchase.  The map pack will be available for 1200 Microsoft points/$15. Yeap, we know. Let the moaning begin.

While many have argued in the past that the oft-controversial pricing of Call of Duty map packs is a way of scamming users, it is difficult to argue that this map pack isn’t worth it relative to some of the others previously released. Containing five full Zombie maps, a few songs and a theme is a lot of content for the price, especially considering what the Modern Warfare 2 maps offered for a similar fee.

But what about those who received the World at War maps with the purchase of the Hardened/Prestige editions of Black Ops? Will they still have to pay the fifteen dollar cover charge to gain access to the extra content? Luckily for them, Activision has it covered.  Players who redeemed the code for the Zombie Maps will receive the extra content (Moon, Moon theme and Zombie songs) for free. As always, there will also be a double XP weekend to celebrate the launch of the map pack, which will take place on Labor Day Weekend.

Activision also included some new screenshots of the Zombie Maps – check them out in the gallery below:

Activision is attempting to milk fans for as much money as possible form their latest best-seller before the Call of Duty XP event kicks off in a month and the focus switches to Modern Warfare 3 which releases this fall. If you missed them, here are our thoughts on the Black Ops DLC released to date – if you hate the prices, don’t blame Treyarch:

Rezurrection lands on Xbox Live August 23rd for the price of 1200 Microsoft points. No word has been given on a PS3/PC release yet though it is safe to assume it will most likely launch a month afterwards as other DLC packs have. Will you be picking up Rezurrection or do you still think the price point is too high to justify a purchase?

Call of Duty: Modern Warfare 3 releases November 8th, 2011.
