Ignited Steel — in an effort to realize its instinct for expansion, humanity has created AI. which controls and manages all the resources needed to expand the human race throughout the galaxy. Soon a fatal error in AI. The FarOS code was detected and could not and did not want to stop expanding. Hoping to stop the expansion of PharOS, humanity depends on the Hot Steel program, a plan based on outdated technology that PharOS cannot control. The old bellows of past wars are now the only hope of mankind. Moving bags require energy and can overheat the fur. When overheated, the bags inflict more damage and become more vulnerable to enemy attacks.
