Update, February 27: Unfortunately, the free Devil May Cry that was going to be offered through Twitch Prime has been delayed because of "unforeseen technical circumstances," and it has been pushed back by a week.
It's somewhat disappointing, but tech issues happen, and the end date for the promotion has been pushed back in kind, so you've still got about a month to collect your copy of Devil May Cry when the promotion starts.
We're still hoping we can soon add Devil May Cry 5 to our list of upcoming PC games.
Due to unforeseen technical circumstances, we are shifting the free distribution period of the original Devil May Cry on @TwitchPrime to March 6 - April 3, 2018. We apologize for the inconvenience. https://t.co/MipIKRuxMA
