Cyber Monday is here, and Microsoft seems to be perfectly content with underwhelming you. Today, you can pick up Gotham City Imposters (600 MSP), Shadow Complex (800 MSP), Bloodforge (600 MSP), Real Steel (400 MSP), and Expendables 2: The Game (600 MSP, lol).
In terms of DLC, there's Expendables 2 "Full Access" (120 MSP, double lol), and Left 4 Dead 2: Cold Stream. Yep, there's nothing here that I'd want, or don't already have.
Out of all of these, if you don't have Shadow Complex yet, get it. Otherwise, you can probably skip this sale entirely. In other news, this actual decent sale is still going on (but they end today).
