Square Enix announced today that a week-long sale on Xbox Live-downloadable games and DLC will have their prices plummet. Sleeping Dogs will be $20, Mini Ninjas will be $10, Deus Ex: Human Revolution will be $15, while Tomb Raider: Anniversary will be $10, as will Tomb Raider: Underworld. On the XBLA side of things, Mensa, Mini Ninjas Adventures, Geon, and Puzzle Arcade will be 400 MS Points, while Lara Croft and the Guardian of Light is 600. Sleeping Dogs’ extensive range of DLC can be had for half-off – taking some things down to a mere dollar, , and Just Cause 2’s DLC is all a dollar apiece as well. This is the best price yet for Sleeping Dogs and its DLC, and the XBLA prices are quite tempting as well.
