Prime members get to play a new set of four games for free through Amazon’s Luna cloud gaming service during the month of May. The free games this month are LEGO DC Super-Villains, Resident Evil 2, Overcooked!, and Time on Frog Island. If you’re a subscriber to the Luna+ channel, new games this month are a bit disappointing. Tormented Souls is the only triple-A developed game being added. The others are retro games which include Breakthru, Express Raider, Super Real Darwin, and Wizard Fire. Those are all Retro Classix games which are usually sold in collection bundles.
