Na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, na, Batman! Yes, that is the sound of Batman: Arkham City coming to PlayStation Plus in April for PlayStation 3 owners. Arkham City garnered praise from gamers and critics alike, as evidenced by its cumulative 96/100 score on Metacritic. With the recent announcement of Batman Arkham Knight, this is a great way to catch up on Batman’s adventures.

PlayStation 4 owners can join up with friends and take down an evil corporation in a new 2D action game, Mercenary Kings. As you explore the island CLAW (that’s the evil corporation) has taken over, you’ll discover weapon parts that you can take back to your base and use to fashion together some new spiffy gear.

There are two other PS3 games this month: Stealth Inc. A Clone In the Dark and Castle of Illusion Starring Mickey Mouse. Stealth Inc. is, as you can probably guess, a game where you should stick to the shadows. The only way to make it out of the lab alive is via some sneaky platforming, so proceed with caution. Castle of Illusion is a proper remake of the Sega Genesis version, not just an HD upgrade. There are new levels to navigate but the goal is the same — save your #1 mouse (that’s Minnie) from the evil witch.

While Vita owners can also enjoy Stealth Inc. (the benefits of Cross-Buy!) this month, they’ll also get Velocity Ultra, an arcade-y space shooter where you’ll teleport around and save other ships, and Pixeljunk Monsters Ultimate HD, a classic tower-defense style game where you’ll need to save baby Tiki-people.
