IGN has a video showing a full match of the unreleased card game; Artifact. Artifact is one of the new games that Valve is currently working on. The animations in the game are gorgeous in my opinion! The first video is a "How to" guide and the second is an entire match.
The official game play video for Red Dead Redemption 2 will be released on August 9th via Rockstar Games, YouTube, Twitch, and Facebook. The game has an October 26th release date and preorders are available on XBONE and PS4. Here is an older cinematic trailer to tide you over until tomorrow.
