Outlast, a PlayStation 4 survival-horror game set in a psychiatric asylum, will be available free to PlayStation Plus subscribers starting tomorrow. The service also has a prominent freebie for the PlayStation 3 with Metro: Last Light, the atmospheric first-person shooter based on the post-apocalyptic Metro series from Russian author Dmitry Glukhovsky.

A PlayStation Blog post also reminds us of a discount for Dustforce, down to $8 tomorrow, and the imminent end of free downloads for the PS3's remastered Shadow of the Colossus.
