Quantum Conundrum free with PS Plus
You'll be able to enter the Cheap Dimension along with all the others in Quantum Conundrum this week, as Airtight Games' physics-shifting puzzle game is free with PlayStation Plus membership.

And if you're still in the mood to solve environmental puzzles, Machinarium's PS3 version is $6.99 for Plus members on its launch day tomorrow, 30 percent off of regular price. Sony is also teasing Vita-related news "right around the corner," in keeping with a previous announcement that the service would arrive on Vita in earnest this month.
