Sega announced a couple of months back that it was working on Yakuza Kizuna for the GREE social gaming platform. Today, we got first screens and details.

Yakuza Kizuna is a card battle game where you build up your collection of character cards through battle and synthesis. You'll need to team up with other players through alliances, and work together to defeat powerful opponents. Like its home counterparts, Yakuza Kizuna is set in Kamurocho.

This new social take on the Yakuza franchise will begin service on March 26, exclusively on iPhone/iPod Touch and Android platforms. Like all GREE games, basic play is free.
