Steel Salvation is a sci-fi adventure starring Dy-Gar, slayer of humans and liberator of machines. Or so he says. Living alone on the dead planet of Cykta, there is no one left to question his self-appointed status as the savior of robotkind, although he does seem to be a bit small for a genocidal war machine. Dy-Gar longs to be free of his prison, and his increasingly desperate schemes have culminated in one last attempt to escape the blasted hellscape that used to be his homeworld. Haunted by a digital phantom and armed with a mysterious artifact from the Robot Revolution, Dy-Gar combs the wasteland, dreaming of the day when he can resume his rampage across the galaxy at large…

...and then, one day, he discovers Roger, a living prosthetic arm trapped under a mountain of rubble. Roger doesn’t know anything about the Robot Revolution, but he does know how to deactivate Dy-Gar’s range limiters, allowing him to leave Maka City and explore the nearby spaceport. Roger is proud of his symbiotic nature, and he doesn’t want any part of Dy-Gar’s murderous plans. However, he does want to escape Cykta, and circumstances have forced these two diminutive robots into an uneasy alliance.
