Microsoft delivers a late Christmas present to Xbox 360 owners, discounting Castle Crashers by more than 50% for one day only.

The Behemoth's Castle Crashers is still one of the best things going on Xbox Live Arcade, and an excellent introduction to the service for folks who found a shiny new Xbox 360 under their Xmas tree this year. It's a bargain at 1200 Microsoft points, but at 560, or $7, it's simply too good to pass up. If you've yet to partake in the frantic 2D fighting action, now would be a good time. You have until the clock strikes midnight.
