Quake II/Supply Station

Level objective
The objective for this level is "Collect the 4 power cubes to restore power to the Warehouse". In addition, you will complete the unit's primary objective by sending the "logistical train" crashing into a closed door.

Strategy
This is another level that presents no particular difficulties, so go about it in whatever way results in the most fun. Finding the Chain Gun at the beginning gives you a weapon that can take down Gunners and Berserkers easily, but don't use it all the time because it chews up ammunition at an alarming rate. There is plenty of Machine Gun / Chain Gun ammunition (and Shotgun too), but you'll run out if you use the Chain Gun in every encounter.

Walkthrough
After entering the Supply Station section, run along the bridge on the right 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. (See Secrets, below.) Head through the side door to continue.

At the end of the corridor is a small warehouse with a lift platform to the second floor, as well as the first Power Cube. Collect it, and the laser barrier will turn off. Removing the power cube from its holder also disables the door behind you, so you must now continue down a corridor to a lift.

After going down the lift, you will find the logistical train. Jump across the tracks and press the button to have it ram through the door ahead, thus destroying it and completing the primary objective. This also provides the second Power Cube. Once the Power Cube is removed from its holder, the train track is de-energized. Jump down beside the track, look for a green button on the floor to raise the ladder, and proceed up to collect the third Power Cube.

The next room is a maze of tall stacks of crates. The exit is located by the west wall, and is via a stairway covered by a sliding floor panel. Press the green button on the wall next to the floor panel to open it. (See Secrets, below.) This leads to the fourth Power Cube, which was left lying on the floor.

Return to the starting area by proceeding forward. (See Secrets, below.) Take the elevator back to the ../Ammo Depot/.

Secrets
This level has three (3) secrets:
 * 1) When you enter the Supply Station, you will see a crate moving around the floor on a hover-pallet.  If you can enter the alcove it occasionally visits, you can collect a Quad Damage.  This secret is easiest to access by riding the crate, jumping onto the two crates in the corner, and waiting for the moving crate to exit the alcove.  In the alternative, push the explosive radioactive container over to the crates, using it to jump up onto the crate closest to the alcove door.  Quick-save the game here and then attempt to jump to the alcove entrance and get inside before the doors close.  This may take several attempts to accomplish.
 * 2) In the large room with tall stacks of crates, near the wall button that opens the sliding floor panel to the room exit, look for a discolored crate to your left.  Shooting it gives access to a Mega-Health item.
 * 3) The elevator platform used to exit the Supply Station hides a secret.  One way to access it is stand on the elevator door until the platform begins to lift.  As the doors close, inflicting damage on you, you'll have a split second to dive into the pit under the elevator and retrieve a Combat Suit.
