I'm surprised of this arcade game, it's a high-resolution dual-screen game made in 1991, graphics are very nice.
The background and character drawing are very good, as well as the design of various weapons, magic and moves, which can almost catch up with Capcom's level.
The difficulty of the game BOSS is relatively low. The plot is an ordinary Raiders of the Lost Ark mode. Rastan among the optional characters looks a bit like Conan the Barbarian to me. I guess the two games should be related.
