Capcom unveiled the Devil May Cry HD Collection in December 2017, bringing an updated collection of DMC 1, 2, and 3 (but not 4 or the DmC reboot) to PC in March. Twitch Prime members will have the opportunity to grab the original DMC sooner than that, however, and more importantly, for free. 

The free DMC will be available on February 27, two weeks in advance of the Devil May Cry HD Collection. Just log into your account, head to the relevant Twitch patch, and stake your claim. If you like, the full DMC bundle will be available for purchase through the Twitch app too, but you'll have to wait for it to go live first.
