Specific prices aren't offered, but games are being marked down up to 75% for the sale, and the list includes, like, everything. All the Calls of Duties, the Halos, the Batmen, Borderlandses, Metal Gear Solid HD, Dead Island, The Orange Box, etc. Even El Shaddai. Check the list after the break for many more.
Yes, these could all be discounted 1% and one game nobody cares about discounted 75%, but XBLM will be worth a look next week just in case.
