New objective: go to sector security and terminate the ops lockdown

Return to the room with the locked doors and go through the one marked 'Sector 3'. Kill the imps and head through the next doorway. Take out the zombies and imps, and then search around for some fresh equipment. Go through the next door, kill the zombie and follow the corridor to the research room. Kill the zombie and listen to the psychiatrist interviewing his (progressively more insane) patient.

Grab some health using the computer panel. Go through the door, kill the imp and follow the corridor to the next room. Kill the zombies and imps, then have a look around. There's a large archive storage unit in front of you. To your right you'll see a ledge, but at the moment it's inaccessible. Use the storage controls to move the box close to the ledge. When it deposits the box, jump on top and operate the controls again. Once you're close enough jump onto the ledge, crawl into the alcove.

Follow the shaft until you reach a new area. Jump down and make your way along the corridor. The security chief left a BFG 9000 locked in one of these rooms. If you go back through your PDA logs, you'll find the code (931). Open the door and take the BFG. Check out the nearby computer panels for some useful information.

Use the panel to clear the air, enter the room and use the nearby control panel to fulfil your objective. Kill the imp and revenant, then make your way back to Sector 2, where all the zombies were locked up. The aforementioned zombies are now wandering around. Kill them and search until you find a new PDA log.

Make your way to the previously locked door, past the cells, and open it. Kill the imps and zombies and head right. Go up the stairs and take the plasma inducer. Go down the corridor and through the doorway. Kill some more zombies and shove the box into the lift. Now take the lift down to the lower level.

Take out the zombies and commando zombies, then make your way back to the scientist. He switches on the teleport device and gives you a new PDA log. Get some health and then go through the doorway marked 'Chamber 1'. Now use the teleport device.

End of level.
