Gorgeous action RPG Hyper Light Drifter (opens in new tab) and both seasons of government spying sim Orwell are two of the four games available as part of a Twitch Prime subscription this month.
The other two are Bomber Crew, which is a bit like a WW2 version of FTL (opens in new tab), and République, an episodic cyberpunk thriller that Jordan enjoyed back in 2015 (opens in new tab). They're all available if you have a Twitch Prime account, which is included as part of Amazon Prime membership (if you have Amazon Prime, click here (opens in new tab) to link your Twitch account).
Hyper Light Drifter is occasionally frustrating, but it's worth playing for how good it looks. As Andy wrote in his review (opens in new tab), it's properly challenging too, which means you feel good when you make progress. After its release, creator Teddy Dief was hired by Square Enix Montreal but left last year (opens in new tab), and is now working on a secret game (opens in new tab).
Phil enjoyed the first season (opens in new tab) of Orwell—I was more luke-warm on the second (opens in new tab), but both have more than enough good ideas to warrant a look. You spy on citizens and uncover a conspiracy by linking together data chunks on a mock computer terminal.
