The Facility's Layout

INFO
The Thermal Power Plant's facility is gonna be kind of confusing to new people, so here is the Facility Layout explained.

Topside
The Topside is where the player spawns after pressing the "START" button. The topside consists of a carpark, a lobby with a receptionist, the Secondary Evacuation Zone which includes the Space Research Storage Port, R&D area, and the Launch Control Center, which include the Rocket to Innovation Odesa Station. Going back to the lobby, behind the receptionist, there is the Main Entrance to the Main Facility, which include the Elevator to the Main Facility, the Shop, and the Warhead Control Area. Once returning back, there is an unopened area. Some info include:


 * 12 sectors (possibly all Sub-Level sectors? W/o Sector I)
 * Exit
 * Atmospheric and Space R&D
 * Cafeteria (possibly Sub-Level 1C's cafeteria)
 * Visitor Center (possibly w/ Info Center)
 * Personnel Accommodation
 * Shop

Sub-Level 1A
This sub-level is minor, with no backstory. The only known things are:


 * It has 5 sectors (Sector A-E)
 * It handles Rad-Waste
 * It has a Fission Fuel storage
 * Has a Hazardous Environment cleanup team
 * Has Biolab access
 * Researching weapons

Sub-Level 1B
This sub-level is very minor, with less information. The only known things is it has 3 sectors (Sector A-C) and the rest are unknown, labeled as condemned. Taking the stairwell to the Sub-Level reveals that the door is boarded up and a label says that the area has been condemned due to a contagious disease.

Main Facility (Sub-Level 1C)
The Main Facility is the largest area in the game. After getting out of the elevator, the area consists of 4 sectors, the 2 main sectors are Sector A | Facility Hub and Sector D | Research and Development. Some info include


 * Having 5 sectors, one abandoned (Sector A-D and I)
 * Sector C's reactor core
 * Sector A's security HQ
 * Sector B's thermal generators
 * Sector D's office complex and Biodome
 * Tram system

Sector A | Facility Hub
There are 2 sectors that are beside Sector A, which are Sector B | Thermal Generators and Sector C | Reactor Core. Sector A consists of the Tram Hub, The Server and Mainframe Room, which where ASAS resides, the Security HQ, the Medical Room, and the Cafeteria, which is a connector to Sector D.

Sector B | Thermal Generators
In Sector B, it consists of the Bunker, the Coolant Controls, Storage Room 2, and the thermal generators.

Sector C | Reactor Core
Sector C consists of the Core Control Room, the Storage Room 1, a connector to Sector D, and the Core Chamber Entry.

Sector D | Research and Development
There are 2 paths of Sector D, the left goes to the Facility Control, while the right is the connector, consisting of the Volcano Entry, PLZ EXTEND

Maintenance Sector and Containment Sector (Sub-Level 2)
[CLASSIFIED INFO]

Almost nothing is known about Sub-Level 2. It is not shown on the elevator terminal, and the door to the stairwell is locked by a keycard reader. Through the door, one can see a trollface. It is mentioned in a freezedown as having suffered multiple high level containment breaches.

Out of IITPP
All sectors in this list don't exist in main game but are official.

Topside | Information Center
Information about this center can be found by clicking here. The Information Center is made by GalacticInspired, a trusted player in IITPP.

Sector D | Corporate Offices
The corporate offices was turned to a standalone game, due to the Offices possibly overlapping a part of Sector D. This game is made through the IITPP Division Group (formerly known as ARFFC).

Trivia

 * Sector A, B, and C were the first sectors.
 * Sector D then followed, and much more sooner, the Information Center and Topside were created.
