A new multiplayer map for The Outfit, and Dead Rising themes make it onto Marketplace, but you'll have to wait to get them.
First up is a new multiplayer map for The Outfit. Titled Arnhem Mayhem, the free map was previously only available to those who bought the game from Best Buy, but is now available over Xbox Live Marketplace. Also added to Marketplace is a host of Dead Rising picture packs and themes, ranging in price from 50 points for some pics, to 150 points for the full theme.
Don't go rushing off to download them just yet though, as Xbox Live, along with Xbox.com and its forums, are closed for maintenance until midnight tonight.
