Capcom first demoed Street Fighter X Tekken at San Diego Comic-Con with a fight between Ryu and Kazuma. While we got to see the game in action, the early build didn’t even have life bars.
Just a few days ago, Yoshinori Ono brought Street Fighter X Tekken to Capcom UK and Ono posted a picture of Capcom employees playing it on Twitter. This build looks further down the line with life bars and what might be a super meter on the bottom of the screen.
Ken is confirmed as a playable character too. You can see him paired with Ryu in this match against Kazuma and Nina Williams. Like the Street Fighter EX series, Street Fighter X Tekken has a tag team system.
