Assassin's Creed 2 is free now to Xbox Live Gold members as part of the Games with Gold program, and stays that way until the end of the month. But don't let the free-runner take all your attention, because there are other Xbox Live Marketplace deals up for grabs this week.
First up, the 2011 edition of Mortal Kombat is slashed in half to $10 this week, which is as good as a fatality discount-wise. Some of its DLC is half-price, too, including the Season Pass, and XBLA entry Mortal Kombat Arcade.
Meanwhile, Capcom has a publisher sale going on this week. We've spotted the very intense likes of Asura's Wrath, Devil May Cry 4, and Resident Evil 5 at $10, while fighters Ultimate Marvel vs Capcom 3 and Super Street Fighter 4: Arcade Edition are at $15, as is the Devil May Cry: HD Collection.
