It's a big day for big games to get comparatively smaller add-ons.
The Skyrim "Dragonborn" DLC launches today on Xbox 360; you'll have to wait until next year to play it on PS3 and PC. XCOM: Enemy Unknown players on all platforms can recruit Zhang today in the "Slingshot" DLC. And Max Payne 3 players can unearth the title character's "Painful Memories" with a set of new multiplayer maps and weapons, though he'd probably prefer leaving them repressed.
He's kind of a downer as it is.
