Major Nelson recently peeled away the veil separating us from the knowledge of when stuff would be coming out on Xbox Live Marketplace over what remains of the month of January. This new knowledge includes the upcoming Deals of the Week -- on January 18, both of the DLC packs for the original Mass Effect will be marked down to 240 ($3) each and Hasbro Family Game Night: Battleship will get rolled back to 400 ($5); and on January 25, Portal: Still Alive will have its price temporarily reduced to 800 ($10). The Major also announced two new Games on Demand: Ghost Recon Advanced Warfighter 2, available now for $20, and Dead Rising, coming January 26 for an undisclosed price. For the rest of January's bounty, including discounted Games on Demand titles, XBLA releases and Avatar items, head past the jump.
