More free games on the way
With less than 24 hours to go in the month of May, Sony has now announced June 2016's lineup of PlayStation Plus free games.

The PlayStation 4 games include NBA 2K16 and Gone Home, while PlayStation 3 owners can pick up Echochrome and Siren: Blood Curse (Episodes 1-12). Freebies for PlayStation Vita in June include Little Deviants and God of War: Chains of Olympus.
The PlayStation Store typically updates on Tuesdays, so these titles may be available later today. If the refresh hasn't happened yet, it's not too late to grab May 2016's free PlayStation Plus games, which include Tropico 5, Bionic Commando Rearmed 2, and God of War: Ghost of Sparta.
