A pair of new offerings has gone up on the Xbox Live Marketplace today, as Xbox Live director of programming Larry "Major Nelson" Hryb has announced on his blog that a demo for Rumble Roses XX has gone up, alongside the belated Perfect Dark Zero Map Pack #1.
The Perfect Dark Zero maps were prematurely announced as being available last week. Now that it's up for real, it includes four new multiplayer maps: Plaza, Trench, Rooftops, and Gas Plant, and sells for 500 Marketplace points ($6.25).
As for Rumble Roses XX, this sequel to the original PlayStation 2 all-female wrestling game was released in March. The game introduces tag-team wrestling to the series, as well as online multiplayer matches. For more on these games, check out GameSpot's final reviews of Perfect Dark Zero and Rumble Roses XX.
