Knightmare II: The Maze of Galious(魔城伝説II ガリウスの迷宮,Majō Densetsu Tsū: Gariusu no Meikyū?), is the sequel to Konami's MSX game Knightmare. While the first game was an overhead, vertical scrolling shooter, The Maze of Galious is a side-view, flick-screen platform game. The player controls Popolon and Aphrodite, entering the evil priest Galious' castle to free their yet-to-be-born son Pampas from the priest's evil clutches. Being able to control Popolon and Aphrodite means the player actually has two lives, and while the characters act slightly different the game stays more or less the same, no matter who the active hero is.
A Family Computer version of Majou Densetsu II was released exclusively in Japan a few months after the MSX release. The Famicom version, titled Majō Densetsu II: Daima Shikyou Galious(魔城伝説II 大魔司教ガリウス?), is a completely redesigned version of the game.
The Maze of Galious offers extra bits and bonuses if The Game Master, Knightmare or Q*bert are inserted in the second cartridge slot available on some MSX machines.
La-Mulana is a homage to MSX games in general and The Maze of Galious especially, and borrows many elements from the game. It also contains a bonus area designed to look like a The Maze of Galious level, in which the MSX cartridge of the original game can be found as an in-game item.
The indie game Unepic also features a homage to The Maze of Galious, where the player enters a "retro" room which features a tombstone that reads "Gamalech", the name of the final boss in The Maze of Galious, and has a very similar color pattern and design.
