Rastan Saga is an action-adventure game released for the Sega Game Gear. It follows the same formula as the original Rastan Saga arcade game, but adapted for the handheld's technical limitations. As a warrior, players navigate through various stages, battling enemies and collecting power-ups to ultimately defeat the game's final boss. The game most likely inherited its core mechanics and aesthetics from the larger arcade game, and was likely developed by a Sega internal team. While it retained the spirit of the original, it simplified many aspects to suit the Game Gear's less powerful hardware. It was known for its fun, fast-paced gameplay despite the graphical limitations of the era.
