United Front's open-world action game, Sleeping Dogs, is now available for free to PlayStation Plus members as part of Instant Game Collection.

Papo & Yo is available for $9 this week (or $12 if you want the soundtrack tossed in), while Retro City Rampage is down to $7.50. Fatal Frame 2 joins the PS2 Classics list, and a multiplayer demo for Fuse teases Insomniac's latest shooter before its launch later this month.
