Milo, a mechanically augmented tunnel rat, steals an MK7 pod to explore *Genesis*, where his tinkering awakens ancient horrors beneath the virtual earth.
Synopsis
Milo inhabits a steel cave within an artificial mountain, a discarded genius maintaining the machinery that sustains his grim habitat. His twisted body, augmented by prosthetics, navigates narrow tunnels and air shafts—his only world. Fixing broken systems is his purpose, though his boredom often leads to reckless tinkering.
When the criminals he once escaped return, Milo seizes the chance to steal their prized MK7 immersion pod, granting him access to *Genesis*, a virtual world of ancient mysteries and subterranean horrors. Now a literal tunnel rat, he delves deep, solving puzzles, forging alliances, and provoking creatures better left undisturbed.
But Milo’s brilliance comes with chaos—and as his curiosity unravels forgotten secrets, the line between fixing and breaking blurs. The real question isn’t whether he’ll uncover the world’s hidden depths, but whether he’ll doom them in the process.
