The final build for Gary Gasko's Retro Remakes 2008 Competition entry was released today, a remake loosely based on the arcade classic Spartan X (known as Kung-Fu Master in the States). This updated version of Kung Fu 2 comes with nine playable stages, unlockable secret characters, and an online high score submission feature. (source: Retro Remakes)
