In celebration of Twitch Prime Day, July 16, the streaming platform's premium subscription service is giving away 21 free games. Between now and August 2, subscribers can pick up Tacoma, Pillars of Eternity, Qube 2, Brutal Legend and many more. 

This follows Twitch Prime's 'Free Games With Prime' initiative that was launched in March and gifts members complimentary games on a monthly basis. Marketing person Robert Busey explains that once downloaded, games are yours to keep. Busey also advises those interested to "check back every day, as the selection will be constantly changing."
