Rastan Saga II is a side-scrolling platformer-brawler game in which the titular character fights demons and undead across a number of stages. Rastan can collect different weapons as he moves towards the boss monster of each stage, becoming stronger after every victory.
The game was originally released to the Arcade by Taito in 1989. It would later see conversions for the Sega Mega Drive/Genesis and the PC Engine. While the PC Engine was Japan-only, the Genesis version was released in North America and the Arcade version in all three territories - however, the Arcade version was named Nastar in Europe and Nastar Warrior in the US. The PC Engine version would later be added to the Wii's Virtual Console in 2009 in Japan only.
