"Rastan Saga (ラスタンサーガ), known in North America simply as Rastan, is a 1987 hack and slash platform arcade game developed and published by Taito.
The player controls the barbarian named Rastan, who has to cross a number of levels and defeat enemies inspired by Greek mythology while avoiding obstacles and traps. The game consists of six rounds with three scenes per round. To clear each round, players must reach the third scene and defeat the castle boss. The player can pick up new weapons by stabbing them with the sword and items by walking over them. Some weapons and items include axes, hammers, fire swords, jewels, shields and mantles. The game's background graphics featured broad landscapes with changing sunlight effects with detail and clarity not previously seen in video games."
