Kiai Resonance

Become a samurai from feudal times in this fighting game where one hit off-guard is fatal. You take part in multiplayer combats, as well as several challenges and mini games to perfect your abilities. The player can change his katana position at any time to adjust to his opponent's, creating a mind game where you have to anticipate his next attack. The graphics are attempting to restore the simple aesthetics of traditional Japanese prints by taking some pictorial elements of its great masters, while imbuing it with violence that characterized the confrontations.
