If you feel like shooting aliens on your Xbox today, you are very likely to be able to do so in a new venue. Both Halo 4 and Gears of War Judgment have new DLC, available at no extra cost.

Having passed certification early, Microsoft has released the Halo 4 "Forge Island" map well in advance of its expected April 11 date. On their own, these aren't the most exciting locations – three big, flat islands – but they're intended to be the base for Forge Mode customization.

Gears of War Judgment's Execution multiplayer is also available today, along with the map Haven, "courtesy of Maxim and Epic Games." Weird. Microsoft warns that you have to download this DLC directly from the title menu or from the Dashboard. "The dialogue box prompting you to download the pack in the matchmaking menu is not functioning properly and will be fixed as soon as possible."
