Sony typically reveals the lineup prior to the start of the month, but said last week that it wasn't ready to do so at the time.
Ubisoft Montpellier's Valiant Hearts and Just Add Water's Oddworld: Abe's Oddysee New 'n Tasty are the two PlayStation 4 games in the list. PlayStation 3 owners get Minority Media's Papo & Yo (screenshot above) and Frogwares' Sherlock Holmes: Crimes & Punishments. On Vita, Roll7's OlliOlli 2 is joined by Dynamighty's CounterSpy.
OlliOlli 2 also launched today on PS4, and CounterSpy is available on PS3 and PS4 as well as Vita. Because Crimes & Punishments is not a cross-buy title, the PS4 version of the game is not available free to PlayStation Plus subscribers.
All six games are now available to Plus members at no additional charge.
