The lead-up to Amazon's Prime Day is in full swing. This year, to drum up excitement for the shopping holiday beginning , Amazon is giving Amazon/Twitch Prime members free PC games each day between now and July 18. All told, Prime members stand to receive a total of 21 free games in July. Five games are free to download today, but you'll want to grab them soon, because they won't be free forever. The games in question are Battle Chef Brigade, Q.U.B.E. 2, and an SNK bundle that includes the Neo Geo games Metal Slug 3, The Last Blade, and Twinkle Star Sprites.

To get your free games, you'll first have to link your Twitch and Amazon Prime accounts. Then head to Twitch.tv and click the crown icon next to the search bar. That opens a drop-down menu where you'll find your free games, along with any other freebies you haven't collected yet. Just note you'll need the Twitch desktop app to access the games.
