If you take Chris’s word for it (and a lot of other people), Splosion Man is one of the best Xbox Live Arcade games of 2009. It was a great game at $10, but next week it’ll be 50% off and you’ll be able to grab the game for 400 Banana Bucks. That’s $5 in human money.

The sale runs all next week starting February 1st, so make sure to peel yourself away from Mass Effect 2 and pick this bad boy up if you don’t own it already. While you’re at, make sure you do not buy Halo Wars from Games on Demand for $29.99. It’s much cheaper used at GameStop and you can resell it later if you want.
