Just in time for the release of Platinum Games' latest, PlayStation Plus offers ... a completely different Platinum game for free. Vanquish is free for PlayStation Plus members on PS3 starting tomorrow. Dust 514's Starter Pack is also free for Plus.
Meanwhile, Vita gets its own free sci-fi action shooter: Mega Man Maverick Hunter X, the PSP remake of Mega Man X. Not at all related to sci-fi shooting, or free, are discounts on both the PS3 and Vita versions of Urban Trial Freestyle, a very familiar-looking bike game.
