Quake II/Supply Station

In the supply station, you will need to destroy the supply train, as well as collect four power cubes required to enter the warehouse.

Logistical train


After entering the supply station section, run along the right bridge and enter the building. Once inside, you will first need to unlock the door to the right by jumping on the stack of crates, and pressing the button. Head through the side door to continue.

At the end of the corridor is a small warehouse with a lift to the second floor, as well as the first power cube. Collect it, and the laser barrier will turn off, allowing you to continue down a corridor to a lift.

After going down the lift, you should encounter the train. Jump across the tracks, and press the button to have it ram the door ahead. This also provides the second power cube. Jump down, look for a button on the floor to raise the ladder, and proceed up to collect the third cube. The following room will be a maze of crates.

The exit to the maze is located somewhere on the left, and is a set of stairs lowered down. This leads to the fourth cube, which was left on the ground.

Return to the starting area by proceeding forward. Take the elevator back to the ../Ammo Depot/

Secrets

 * 1) When you enter the supply station, you should see a crate moving around the floor.  If you can enter the alcove it occasioanlly vists, you can collect a quad damage.  This secret is easiest by riding the crate, jumping on the corner two crates, and waiting for the moving crate to exit the alcove.
 * 2) In the maze of crates, look for a discolored crate to the left of the entrance.  Shooting it gives access to 100 health.
 * 3) The elevator used to exit the supply station contains a secret.  If you can get under the elevator (which may require taking damage), you can collect armor.
