*The Astyanax, known in Japan as The Lord of King, is a side-scrolling action game developed by Aicom released for the arcades by Jaleco. A home version for the Nintendo Entertainment System, simply titled Astyanax, was released a year after the arcade version
Unlike the arcade version, the NES version can only be played by one player. Like in the arcade version, the player has a life gauge, a strength gauge that fills automatically when he is not attacking and a magic gauge for his spells. Also unlike the arcade version, the player can wield other weapons besides the default axe, as well as use different magic spells, which are selected by pausing the game.
