Quake II/Lost Station

Level objective
The Lost Station is a secret level, where your objective is to find a Super Shotgun. While it will help you in this level, another Super Shotgun can be found in the final room of the Installation level where you'll be returning after finishing the Lost Station level.

Upon exiting the elevator, you should see a Shotgun to your left. Walk down the corridor until you see the cargo lift; if desired, you can collect a machine gun to your right. (See Secrets, below.)


 * Tip: If you already have a particular type of weapon or other item, attempt to pick up an additional one when you encounter it.  You can carry multiples of most items and, where applicable, each one adds to your ammo supply.

Observe the cargo lift. There are two lift cars; choose the one that carries a First Aid Kit. Ride the cargo lift to the second area. Go through the door, and when you reach the stairs at the top of a ramp, turn around and shoot the button. This allows you to collect the Red Key. (See Secrets, below.) Continue along the original direction of the stairs.

At the end of the path is a cavern with a tower in the middle of pond. Take the lift platform on the side to the top of the tower, and use the Red Key to lower the drawbridge. (See Secrets, below.) When you collect the Super Shotgun, the level objective is complete, but more enemies will appear throughout the level as you return to the lift that takes you back to the Comm Center.

Walkthrough
From the elevator, take a left and follow the only available route. As you will be coming back this way, consider leaving the health and ammunition that is scattered around to be picked up later, when you may need it more. You will meet two Guards, turn to the right and then arrive at a square door. If you approach the hatchway that you passed on the left, you will receive the message "ACCESS DENIED Door is opened elsewhere". Through the door that does open is what looks like a subway platform with some packing crates and exploding barrels on it. Periodically, one of two tram cars stops briefly at the platform and then continues. There are two Enforcers here, probably around a corner to the right. Keep clear of the barrels as you fight them.

Secrets
This level has six (6) secrets, plus a bonus:
 * 1) Upon entering the upper cargo lift area, head to the room on the right.  Jump up to the top of the crates and drop down behind them to find a Silencer.
 * 2) In the upper cargo lift area, jump into the water.  Swim to the left and find the underwater entrance to a corridor containing an Underwater Breather and various other items.  The corridor ends at a door leading back to the entrance to the first cargo lift area.
 * 3) In the lower cargo lift area, dive into the water.  Shoot the wall button to the left to open a secret underwater door in the opposite direction.
 * 4) The wall button that raises the ramp to provide access to the Red Key also reveals a secret area under the ramp.  If you stand just below the button as you shoot it, you can jump off the ramp before it rises, then turn around and run into the secret area beneath it.
 * 5) An Adrenaline vial can be reached by shooting a wall button.  This triggers an array of wall-mounted shooters.  Jump down and into the door on the left to reach the Adrenaline vial.
 * 6) Below the drawbridge leading to the Super Shotgun, there is an underwater door at the base of the tower.  It contains two Barracuda Sharks and also leads to an Invulnerability item.
 * Bonus: — If you ride the cargo lift around the loop 13 times, the sign on the wall opposite the lower station platform is replaced with the image of a bloodied rubber duckie.
