Microsoft has made the great decision that they need a huge DLC sale! Halo: Reach, Gears of War 2, Fable III, Forza 3, Crackdown 2, Alan Wake, Halo 3, and Halo Wars are all part of this sale. Most DLC is 50% off which is awesome. Also, the current deal of the week is Mass Effect 2 DLC at 50% off. There may not be any new games coming out, but Microsoft sure knows how to entice us to spend our money ;p
The Microsoft DLC sale runs until July 27th, and the Mass Effect 2 DLC until August 1st.
