Green Zone - Contaminated Zone
Blue Zone - Marked Section
The path to the exit has been sealed by the security systems. The gate must be opened from the Power Control Room.
The PC reaches the control room, but the system requires access override to open the gate.
The system message suggests contacting the Maintenance Supervisor.
At the exit of the room, two signs indicate:
The PC moves right towards the MSO, but the corridor doors are locked.
A detour is required. However, toxic fumes block the way.
Before proceeding, the player must reactivate the ventilation and purification systems.
The PC heads toward the Fan Control Room.
Inside, there’s a partial map showing only the Fan Section.
Screens indicate ventilation failure — “Main Exhaust Failure”.
Nearby lies a Diagnostic Tool
The PC proceeds to the Main Exhaust Fan area — where cables are found chewed through. Parts of the room seems to be... eaten.
New cables are needed to restore power.
The Storage Room, which contains spare cables, is initially locked.
The Storage Key can be found in the Social Room.
On the way, in the Locker Room, the PC finds ammo and a note:
“Damn tunnels. I keep getting lost down there.
I finally marked the corridors.
Maybe I shouldn’t have used my initials...”
The note lies under a locker labeled Robert McCulling.
When the PC returns with the Storage Key, a hatch collapses and hatched insect creatures attack near the Storage entrance.
Inside Storage, there are replacement cables — but their types are not labeled.
The PC must return to the Diagnostic Tool to identify each cable type.
The device requires two types of connections:
POWER
CONTROL
R_max = (V_src - V_min) / I_req
Where:
R_max: Maximum allowable cable resistance
V_src: Voltage at the generator source
V_min: Minimum voltage required at the device slot
I_req: Required current at the device slot
Using this formula, players calculate the maximum resistance allowed for each slot and select an appropriate cable.
If cables are too short, players can connect multiple cables using connectors.
The total resistance is calculated as the sum of connected cable resistances:
Players must ensure:
The PC returns to the control room and reactivates the ventilation system.
Toxic gases in the tunnels begin to dissipate.
The PC proceeds into the tunnels — now navigable but dark and infested.
The Service Tunnels form a damp, maze-like labyrinth filled with faint light and lingering haze.
The player can use Robert McCulling’s markings (“RM”) carved on walls to navigate.
Midway, the PC discovers a Tunnels Service Room — a save room with supplies and a map of the tunnels, providing clear guidance toward the exit.
Eventually, the PC reaches the Maintenance Supervisor Office, finding the Keycard and additional ammunition.
The PC uses the Keycard to unlock the gate.
However, the main tunnel leading out is collapsed.
The PC enters a side section — a narrow, dim corridor system.
This area, once full of toxins, now serves as the nest of a giant mutated beetle.
The PC steps through the newly revealed passage —
a secret tunnel few ever knew existed...
