As a reminder, the previously Xbox 360 timed-exclusive Call of Duty: Black Ops "Escalation" map pack is now available on the PlayStation 3. The pack costs $14.99 and is available through the recently restored PlayStation Store.

As previously reported, the pack includes four new standard multiplayer maps -- Hotel, Convoy, Zoo, and Stockpile -- along with a "Call of the Dead" Zombie mission that includes more celebrities than some films.

If you don't own Black Ops or a PS3, Activision and Sony recently released a new bundle of the two for $299.99. It also includes the First Strike downloadable content.
