Samurai Shodown VI is set to launch on the PS4 via the PS2 classics program in North America on November 22nd.
Like with all PS2 games re-released onto the pS4, you can expect (though it hasn't been officially confirmed) Samurai Shodown VI to be up-rendered in 1080p, and come with trophies (and hopefully a platinum), as well as remote play.
PlayStation Blog provided the following blurb about the 2005 fighting game:
The age: Tenmei. The venue: the world. The prize: glory. The curtain now rises on the samurai world’s greatest spectacle. Let the games begin!
