In the distant future, to improve the quality of their war-robots, a star civilization decides to organize special tournaments. Those "metal combats" are held in arenas where two robots fight against each other in a death match. A vast list of components can be edited and customized from the start and the game counts seven different types of robots.

It is the year 2600 of the Glorne Calendar. On the planet Deek, which boasts the highest production of robots with artificial intelligence in the universe, an event called “Metal Combat” is held to upgrade the combat robots known as Metal Soldiers. A special arena, Beriaside, has been prepared, where the robots’ capabilities are put to the test, forcing them to engage in fierce battles again and again.
