TBM ( tunnel bore machine)

[TechStack]

Feed it tracks so it can go forward.

May:
Need to be hauled by wide bed truck.

Maybe 4 huge components that would be needed hauling in the wide bed truck.
if player picks up maybe a debuff on speed (slowness) for hauling such heavy components.

Drills huge world hole.
leaves behind some type of support blocks.

requires massive amounts of fuel.

maybe so the drill head wears with time.
