Ra Gias, the land of magic and alchemy, is the world that exists in the underground. The Kingdom of Langran is a country of this land. One day, a word of thunder came from the Academy of Alchemists. To cope with this danger, Langran summoned all alchemists to create a type of robot combined with magic called “ElementalGod-Machines.” The coming of a god of destruction – Shiva Volkruss will bring a fatal disaster to the whole land of Ra Gias. Based on this plot, Super Robot Taisen OG Saga – Masou Kishin I & II is a turn-based strategy simulation game in which you will be the one to organize the ElementalGod-Machines team to attack and defeat enemies. Each ElementalGod- Machines will be able to move a certain distance in the map and attack the nearest enemy. Each Machine has three main indicators: HP, MG, and PN. When HP reaches zero, the unit will be removed from the playing field; MG is the index showing the road segment that the unit can move during the game, and PN displays the attack power. If you destroy all enemies on the field, you will win.
