Today's Xbox Live Marketplace sale consists of Gears of War 3's "Season Pass," which, if you didn't already know, gives you the first four downloadable add-ons at a discount. Today's price is 1800 Microsoft Points, or $22.50, which is 25% off the regular price. Not a bad deal if you were in the market for it.
Two of the first four downloadable add-ons have already released--the "Horde Command Pack" and "RAAM's Shadow." The next one up is "Fenix Rising," which will have you revisit Marcus' past and also adds a new ranking system for multiplayer. "Fenix Rising" is due out January 17.
Oh, and you can also snag the "Gears 3 Skins Launch Collection" at 1800 Microsoft Points today, if you have an extra $22.50 laying around.
