Microsoft is taking a set of sharp blades and ravenously cutting prices across the board on Xbox Live Marketplace content, starting right now. Already inexpensive (and wonderful) title Outland will cost you a cool 400 MS Points ($5), while deep multiplayer fare like Monday Night Combat and Section 8: Prejudice are going for 600 MS Points ($7.50) and 800 MS Points ($10), respectively.

Also, hey, if you're not one of the over 2 million people who own and adore Trials HD, here's another chance to grab it on the cheap (600 MS Points/$7.50). It's unclear when the "Extreme Shopping" sale will end, so we've asked Microsoft for more info. For now, enjoy the sweet, sweet savings while you can.

Update: This post originally had ilomilo listed as on sale for $5, which is false. Sorry about that!
