Amazon Prime subscribers can claim 13 free games during the month of June. Well, at no extra cost to their Prime subscription, anyway. That’s on top of the recently announced extras that are available for the next few weeks, including Turnip Boy and Calico. But next month’s lineup of freebies - which includes the ever-lovely SteamWorld Dig 2, Neverwinter Nights and Autonauts - starts on June 1st, with more free games being made available every single week after that, so be sure to check back every Thursday.
