With such large collections, Xbox and PlayStation have been releasing free games in different ways for months now, but PlayStation's April offerings look like some of the best yet. Subscribers to the PlayStation Plus service will be able to play the kick ass retro, multiplayer shooter Mercenary Kings on PlayStation 4.

Other offerings come in the form of PlayStation 3 games Batman: Arkham City, A Clone in the Dark and Castle of Illusion Staring Mickey Mouse. As well as two titles for the PlayStation Vita in Velocity Ultra and Pixeljunk Monsters Ultimate HD. While most of these games probably aren't worth getting at full price, they are definitely a worthy distraction for you PlayStation Plus bucks.
