Major Nelson has posted the schedule for upcoming Xbox Live content, replete with plenty of new releases and deals. We knew most of the XBLA release dates already, including March 7 for I Am Alive and March 14 for Shoot Many Robots. What we didn't know was the March 14 release of Defenders of Ardania, a fantasy tower defense game we first heard about over a year ago.

Beyond XBLA, this week's Deal of the Week sees Borderlands DLC heavily discounted, in most cases by 50 percent. Next week's deal will slash prices on several dungeon crawlers, including Dungeons & Dragons: Daggerdale, The Baconing, Torchlight, and Warhammer 40,000: Kill Team, all of which will be 50 percent off.

Finally, a Dead or Alive 5 demo is slated for March 19, presumably the one of the same demos included with Ninja Gaiden 3 (which is totally coming out this month, lest you forgot). Head over to Major Nelson for the full content schedule.
