Sony revealed the PlayStation Plus free games of March today through the official PlayStation Blog. We don't have individual release dates, but titles tend to roll out early in the month.

PlayStation 4 owners will have access to Dead Nation: Apocalypse Edition, a revamped edition of the game previously released for PS3 including "updated visuals and controls."

PlayStation 3 owners will have access to:

And PlayStation Vita owners will be able to download:

Unit 13: a third-person shooter that includes two-player online co-op.

Monster Hunter: Freedom Unite: The PSP version of the monster-killing simulator, which also happens to be playable on your Vita.

PlayStation Plus is Sony's subscription services for all of their consoles. A standard one-year membership costs $50 and nets users access to a collection of free games like the above, although you lose access if your subscription expires. On PlayStation 4, a Plus subscription is required to access online multiplayer.

To that end, the PlayStation Plus games from February will expire soon, so if you're a member and you still haven't downloaded Outlast, Metro: Last Light, PayDay 2, or any of the others, you might want to get on that.
