Put in a preorder at the Microsoft Store for some of the hot upcoming games for Xbox 360 and you'll get 1600 Microsoft Points ($20) for free. Good stuff like Tomb Raider, BioShock Infinite, GTA 5, Metal Gear Rising: Revengeance and even Lost Planet 3 are among the listed. Hit up the Microsoft Store to see all eligible titles.
You've got some time to think about which games you'd like to preorder as this deal is good through early April. Note that you can only order up to three games with this promotion.
