Amazon Luna cloud gaming recently pulled its Mac and Windows PC app clients down but that shouldn’t stop Prime members from playing the set of four new games available to them for free. For the month of June, if you have a Prime membership you can play Batman: Arkham Knight, Citizen Sleeper, SteamWorld Heist: Ultimate Edition, and Monster Harvest for free through the cloud gaming service. For those of you subscribed to the Luna+ channel, you’ll be seeing Persh and Haven as two new games being added to your subscription sometime in June.
