The game is a tactical role-playing-game that uses a "Rotation Battle System" in which seven characters are placed on an isometric grid, and fight enemies in a similar pattern on the opposite grid. The same gameplay was later used in the 2003 game Venus & Braves.
After completing "The Cavalry of Molmorth", a new mode titled "Almethera Nendai-ki" (アルメセラ年代記 Arumesura Nendai-ki?, lit. "Almethera Chronicle") becomes available, which has a different story and a higher difficulty level. The "Almethera Nendai-ki" mode was released separatedly for mobile phones on December 1, 2009.
