Tekken 7 has been released only in Japan so far, and in the west we can get our hands on it only at events. The NorCal Regionals 2015 were one of such events, and the game was playable on the show floor.
If you couldn’t go, luckily Youtube user KaosGaming recorded all the matches of the third day of the event at the source of Madcatz’s livestream, and uploaded them in spectacular 1080p and 60 frames per second.
You can check them out in the playlist below, summing up to over five hours of gameplay. If you want to watch the recording of the first day, you can find it here.
