For a limited time only, Microsoft is slashing the price on select downloadable content purchasable from the Xbox Live Marketplace, in what company marketeer Larry “Major Nelson” Hryb calls the “Extended Play Download Days.”

Up for grabs is Bioware’s “Bring Down the Sky” Mass Effect content pack for 300 Microsoft Points, a 25 percent reduction. Other notable cuts include the Shivering Isles expansion, priced at 1600 Microsoft Points instead of 2400 Microsoft Points. Hit the jump for the full listing of price reductions.

According to Hryb, the promotion will run through the end of October.
