Called Games with Prime the first month of free titles include Superhot, Oxenfree, Mr. Shifty, Shadow Tactics, and Tales from Candlekeep: Tomb of Annihilation. No a bad bunch at all. For Australians access to Twitch Prime is free for any Amazon Prime subscriber - you'll just need to link your accounts.
The five free game trend will continue next month with the excellent Tales from the Borderlands from Telltale, SteamWorld Dig 2, Tokyo 42, Kingsway, and Dubwars.
No word yet on how the games will be delivered, so be sure to keep an eye on Twitch Prime
