We've reached the end of all things (for Mass Effect 3). BioWare and Electronic Arts announced the final DLC blast for the 2012 RPG in a press release, with the multiplayer-focused Reckoning set to arrive on February 26, 2013 and the campaign-focused Citadel to follow one week later, on March 5.
Reckoning is yet another free Galaxy At War add-on, bringing an assortment of unspecified "new firepower and character kits" into the co-op survival mode. BioWare will offer a peek at the content on February 25 via its Twitch channel at 9:30am PT. Citadel is a $14.99 / 1,200 MS Points add-on that returns Shepard and his crew to the Citadel for one last hurrah.
