Crimson Dragon got a major facelift this week, with a new update adding a new multiplayer mode for co-operative play over Xbox Live as well as a new difficulty level (Insane) for those not satisfied with the current difficulty options. The update is free and users will be prompted to download the 4GB update the next time they launch the game.

Also, Major Nelson announced on his blog that Crimson Dragon will have a 20-25 percent discount (depending on region) this week, starting January 28 and ending on February 3. In North America, Crimson Dragon is currently on sale for $15 (plus tax).
