From the official Press Release:
Regarded as one of SNK's greatest games ever produced, SAMURAI SHODOWN II successfully integrated a brand new, dynamic fighting system that was years ahead of its time. The fighting system introduced players to several new offensive and defensive maneuvers including the ability to roll both forwards and backwards, ducking to avoid high attacks, hopping to avoid low attacks and the implementation of a 'parry' system that would allow players to deflect incoming attacks at the last second if performed successfully. In addition to the newly revised fighting system, SAMURAI SHODOWN II also features 16 unique playable characters, hidden bosses, a two player versus mode and of course all of the wonderful translations fans have grown to love.
Samurai Showdown II will be available for 900 Wii Points. Additionally, SNK Playmore is also releasing the Samurai Showdown Anthology later this year. The game will collect six games from the series.
