Enpro Plant: Energy Processing and Storage

"Marine. Bravo Team is down. Their operational status is unknown. They were carrying a military transmission card. It's vital you retrieve that card as it contains encoded data needed to send the distress signal to the Fleet. You're the last hope to get reinforcements. Find that card and find it fast."

- Sergeant Kelly

Enpro Plant: Energy Processing and Storage is the ninth level of Doom 3. It begins with Bravo Team being ambushed and wiped out, save for a single survivor. The Lost Soul is introduced in a cutscene, and Wraiths first appear here as well.

This is also the level where The Lost Mission begins.

Summary
The level begins with Bravo Team being ambushed and massacred by the demons. During the fight, one of the marines accidentally shoots a coolant pipe. The damaged pipe releases excess pressure (which had built up due to workers' negligence) which destroys one of the main reactor's cooling rods, causing the reactor to overheat.

The player is subsequently given two tasks: fix the damaged reactor, and retrieve the transmission card from Bravo Team. A sentry bot assists the player during the first part of the level.

After getting down to the reactor and replacing the cooling rod, it is shown that Swann and Campbell were searching for the transmission card as well, but they didn't find it, as it was kept by a surviving member of the Bravo Team. Swann and Campbell then use a car to drive to the Communications. The player fights his way to Bravo Team's location, where he meets up with this survivor. The survivor gives him the transmission card, but is then killed by a wraith. With the card in hand, the player exits the Enpro Facility and heads to Communications Transfer.

Note: it may seem that this level is timed due to the announcer constantly saying that the reactor temperature is rising, but it's actually not, so the player can play through at any pace they want.
