The First Strike Map Pack for Xbox 360 is live. Only 1200 Microsoft points. 646.37 MB
If you are having trouble downloading it I suggest that you wait [insert arbitrary number] minutes, then try again.
Make sure you install the right language version.
Notice - anyone who mentions anything about console differences will have their comments deleted on sight. If it keeps happening, commenting will be stopped. Use this blog to discuss the new map pack, not compare the two consoles or call me Hitler (lmao) --Callofduty4 18:18, February 1, 2011 (UTC)
