The next few weeks of Xbox Live Marketplace content have been detailed by Microsoft's Larry Hryb, including some anticipated XBLA games and discounts on 2K titles.

The twin-stick shooter Gatling Gears will be up tomorrow for $15 (1200 MSP), and Sega Rally Online Arcade will go up next week for a cool $10 (800 MSP). Hryb also tweeted separately that Star Raiders will be up this week as well.

The "Deal of the Week" discounts for this week slash 50% off various DLC content from 2K Games. That includes Joe's Adventure and Jimmy's Vendetta from Mafia 2, Minerva's Den and The Protector Trials from BioShock 2, and the Secret Armory and New Revolution content in Borderlands. Plus, you can snag discounts on game-themed Avatar items like a fedora or Big Daddy helmet.

Next week, the DotW goes pirate-themed, with discounts on Age of Booty, Deadliest Warrior, and The Secret of Monkey Island: Special Edition.

The Retaliation Map Pack for Crysis 2 is due on May 17, alongside the Shift 2 "Speed Hunters" DLC.

Finally, Dirt 2, Operation Flashpoint: Dragon Rising, and Vanquish have been added as Games on Demand starting today. Fable 3 will join them next week, with a demo for the PC version as well.
