Welcome to the tunnel maintenance crew. If the generators fail, it's your job to fix them. Check what's wrong, craft all the needed parts and deliver them. It's simple. Just stay clear of anything that randomly cracks bolts of electricity, spews fire, throws sharp pieces of scrap at high-velocity or radiates with ominous green light. Features: Enjoy claustrophobic penal labor. Break and panic under constant time pressure. Dodge deadly projectiles and safety violations. You may even... kiss a ghost?
