As usual, the PlayStation Store will be updating later today and when that happens, PlayStation Plus members will have access to two free titles: Saints Row: The Third and Gods Eater Burst. As most of you probably know, the former is a PlayStation 3 game. But while Gods Eater Burst came out on the PSP, the portable game is also compatible with the Vita.
Additionally, the PlayStation Blog stated that soon, Sony will be ready to share more news about how PS Plus will work on the upcoming PlayStation 4, so look forward to that. While you wait for the next generation of consoles to arrive, Plus members can play Saints Row: The Third and Gods Eater Burst.
