Phobos Labs - Sector 3: Main Reactor

Phobos Labs - Sector 3: Main Reactor is the ninth level of Doom 3: Resurrection of Evil. The player must shut down reactor and life support systems in order to bring the Phobos teleporter back online.

Summary
The marine returns to SkyTram Station South from Sector 2 and boards the tram to Sector 3. After arriving there, he goes through Reactor Systems and finds the Reactor Core, which he needs to shutdown. The door to Reactor Control is locked with the keycard. To obtain the keycard, the marine needs to use lifts to ride to the bottom of Reactor Core and get to Lower Maintenance, where the keycard is located on the lowest floor. He then rides back, accesses Reactor Control and shutdowns the reactor.

After doing so he activates a bridge using a control panel just outside of Reactor Control and goes to Reactor Support, where he rides an elevator and gets ambushed by a serious amount of monsters. Then he enters Energy Processing and finds a sentry bot which helps him getting through this area filled with monsters. In the end, the marine finds an elevator that takes him to airlock. After going through a very short surface area to the next airlock, he finds another elevator that takes him to Lower Cargo Tunnels. Inside them he fights more monsters, including Hell knights.

After going through all this madness, the marine finds Environmental Control where he shuts down Life Support Systems and leaves Sector 3 via a nearby airlock.
