[IMGW]http://media.1up.com/media?id=3342239[/IMGW]Lost amongst the hubbub of http://en.wikipedia.org/wiki/Independence_Day_%28United_States%29 http://en.wikipedia.org/wiki/Canada_day, http://www.1up.com/do/newsStory?cId=3160812 and http://www.1up.com/do/newsStory?cId=3160820, Sierra dropped the Nightmare map pack for http://www.1up.com/do/gameOverview?cId=3150311 on Xbox 360. Now available on the Xbox Live Marketplace, the pack adds four new multiplayer maps that correspond with the http://www.1up.com/do/newsStory?cId=3160575 added to the game last week.

On the Conquer All and Capture the Flag side, Heliport offers up close quarters battles, while Spill Kill contains a mix of tight sewer segments and open spillways. Those looking for Deathmatch or Control battles can hop onto a pair of self-explanatory maps: Asylum and Cafeteria.

The Nightmare pack is available now for 500 Microsoft points ($6.25).
