Objectives[edit]
- Close 3 of the 4 fire doors.
- Evacuate within 60 seconds.
Although the mission briefing states to close all four doors, that statement is incorrect.
Level[edit]
There are four fire doors on the level, and three of them need to be closed.
The first fire door to close is at the upper-right corridor. Collect the key just north of the door first, and shoot the green switch from the right-hand side of the door.
Next, head to the south, and walk past the fire door without shooting it closed. You should eventually reach a second fire door. If desired, you can go past it to the information terminal, and collect two keys in the south west. You may also head to the north-west section, and unlock the security door on the right to collect 7 extra keys. There is no further need to open the array of security doors; they serve only as a means to absorb keys or ammo.
Now, you should begin to exit the level. Stand to the right of the south-west fire door, and shoot the green switch to close it. Continue right, and close the second fire door as well.
This starts the 60 second countdown timer. Return to the starting area to exit.
