Dome tunnels

The Dome tunnels is the 4th sub-level of the Boulder Dome. This area of the dome is not accessible to the Prisoner until they are at least to part 2 of the game. This level is toxic and irradiated; the only way to survive here is by wearing an environmental suit like the members of the infected scientist team are wearing.

 * 3: Robobrain rechargers - put here to guard the access elevator to the ZAX Mainframe


 * 4: Not mentioned


 * 5: Sleeper chambers - rows and rows of sleeper tanks; only one room is actually accessible to Prisoner


 * 6: Another sleeper chamber


 * 7: Think Tank - brains in the aquarium; these were the early people who tested with CODE


 * 8: Reactor access - here's where the Prisoner can fiddle with the main reactor for the dome, and even fix it if they're skilled enough


 * 9: Purification center - handles water, air and temperature; flooded with toxic gas (damaged)


 * 10: Morgue - many dead bodies with brains extracted, dating to pre-War times; some are in better shape than others


 * 11: Not mentioned


 * E: Exit/Elevator - bottom right corner exit leads to the ZAX level; the one near the center leads back up to the Boulder Dome level 3
