Getting to the Exit (14)

In the area with the IMF logo, use the computer to open a wall section containing a Pig Cop and an RPG. This same room has a wall section leading to SECRET 5.

In the Janitor Closet, grab Pipebombs and break the fan. Enter the grate.

You'll find another fan facing downwards with Laser Tripbomb (a type of explosive trap) lasers. Throw a Pipebomb at the unbroken fan to destroy it.

Backtrack to the Red Key Door Room. The Pipebomb explosion will cause a chain reaction.

After the explosions, return to the vent and go beside the fan facing downwards.

In the Console Room, avoid touching the floor to prevent an enemy attack. If you missed SECRET 5, return to get the Jetpack now.

Use the Jetpack to drop through the vent. Hover to the large red button on the wall and press it.

Four switches will rise opposite you; press them in the order Orange, X, Orange, X.

A compartment will open opposite the switches containing another switch; press it to unlock the large safe door in this room.

Hover out of the room. You can now fight the enemies that would have attacked if you landed on the floor. Rig the room with Pipebombs or Laser Tripbombs beforehand. Run in and out to detonate them. Four Enforcers, Troopers, and Pig Cops will emerge. Defeating them yields spoils, two Pistols, and two Small Medikits (a healing item).

Go up the stairs in Security Access. Near the wall, two Enforcers, a Pig Cop, and a Mounted Gun will attack. Use a Pipebomb to defeat them. Enter the room for a Large Medikit (a healing item). Press the console to open the Security Access door.

In Doors Hallway, doors open automatically as you approach. After the second door, destroy the grate on your left and enter.

In the Excavation Room, you will be attacked by a Pig Cop and a Trooper from the room ahead, and an Enforcer to your left. A Trooper is also in the mine cart. Find two Pipebombs and Chaingun Cannon Ammo (ammunition for a powerful weapon) in the area.

Enter the door near the mine cart to find two Commanders and two Troopers. Defeat them and collect a Small Medikit.

Behind the rock wall, find a Devastator (a powerful weapon) and a Small Medikit.

Find SECRET 7: A switch near the vent you exited to enter this room opens the mine cart door, revealing Shotgun Shells (ammunition), Chaingun Cannon Ammo, an Atomic Health (a large health boost), and two Small Medikits.

Return to the Doors Hallway. Go to the end and use the phone to descend on a platform.

In Offices, you'll see a Pipebomb and a crack in a door. Use the Pipebomb to destroy the crack and back away.

Among other enemies, including Enforcers and Pig Cops, you will fight your first Alien Drone (an enemy with a Shrink Ray weapon). Be careful of its Shrink Ray.

The door to your left will blow out. If you enter to get Pipebombs, the door across from it opens, revealing three Pig Cops. Consider rigging the other door. Another Alien Drone may attack.

Return to where you blew up the wall and get two Large Medikits from the hole.

Hit the Exit Symbol to finish the level.
