Maou Golvellius (魔王ゴルベリアス, lit. “Devil Golvellius”) is an action role-playing video game developed by Compile and originally released for the Japanese MSX home computer system in 1987. Later that year (1988), Compile released yet another remake for the MSX2 system, titled Shin Maou Golvellius (真・魔王ゴルベリアス, lit. “True Devil Golvellius”). This game featured mostly the same graphics as the ones in the Sega Master System version, but the overworld and dungeon layouts are entirely different.
Enter the world of Golvellius. Where demons rule the valley of water… and control the creatures of land, sea and air. Where almost everyone stands against you. There is only one way in… and no way out except victory or death! It’s an adventure that will take you across deserts and mountains, oceans and forests… through eerie graveyards and caves filled with danger and surprise. Golvellius has a password save feature that lets you keep all your possessions. So you never have to start an adventure empty handed!
