I may never know...
Can't play the campaign game because maps can't be found while on Steam. Don't know if it's a download issue or a Steam issue and support from them is really opaque. The cloud never fails to underwhelm me.
Call of Duty: Black Ops takes players to conflicts across the globe as elite Black Ops forces fight in the deniable operations and secret wars that occurred under the veil of the Cold War. Featuring an epic single-player campaign, an incredibly deep multiplayer experience and expanded co-op gameplay, Call of Duty: Black Ops runs on the improved World at War engine and offers amazing enhanced graphics, streaming texture technology, and superior lighting effects.
The included First Strike DLC gives you 5 incredibly diverse maps spanning the globe, including 4 new multiplayer maps and a chilling new Zombie experience, all at no extra charge!
