Today Microsoft launched a holiday promotion called 12 Days of Xbox Deals. From now until January 2nd, they'll be offering discounts on games and other content on Xbox Live. They're kicking off the event with a deal on Xbox Live Arcade title Bastion.

You can pick up the action RPG for 600 MS Points instead of its usual 1200 MS Points. This offer will expire at the end of today. It will no doubt be replaced by some other high-profile bargain tomorrow.

If you'd rather not be rushed while shopped, note that a lot of Xbox Live content will be offered at lower prices until the 2nd. The DLC, Xbox Live Arcade games, and Avatar items listed below are all available at a 50% discount:
