Tunnel Rat: Causing Trouble in Two Worlds
The Walrus King
Milo lives in a steel cave within a man-made mountain of steel and concrete. He spends his days repairing the machinery that keeps the habitat livable and tinkering with prosthetics that help his twisted body move through small tunnels and air shafts — as much discarded machinery as the equipment he keeps running. A super-genius bored with maintenance, Milo steals a new MK7 immersion pod used to enter the world of Genesis when the criminals he escaped from return. Volumes 1 to 4 are available on Kindle Unlimited, with Volume 5 arriving end of 2026, bridging a gritty sci-fi habitat and a virtual fantasy world where he can cause trouble in two realities at once.
Progression: Virtual Reality + Explicit Progression System across two worlds. Royal Road genres Virtual Reality/Progression/Non-Human Lead confirm a central, structured advancement ladder. Milo, confined to a steel-cave habitat as a twist-bodied prosthetics tinkerer, advances by entering Genesis via a stolen MK7 immersion pod — a classic LitRPG/VR level-gated progression where virtual-world gains feed back into real-world survival and vice versa. The VR system gates power through immersion-pod access, Genesis levels, and cross-world resource stealing from criminals. Comedy and non-human lead tags underscore sustained, system-driven growth rather than one-off power-ups. 1895 pages, 5M views and 4.77/3324 ratings corroborate long-form progression-driven advancement; Volumes 1-4 on Kindle Unlimited demonstrate commercialized level progression with Volume 5 in production.
