Quake II/Ammo Depot

Arsenal
Starting the Bunker Area unit, you should have the following armament:
 * Blaster
 * Shotgun
 * Super Shotgun
 * Machine Gun
 * Grenades

Map start
In the starting room, collect a Super Shotgun on the lower level. (See Secrets, below.) Exit the double door in the southwest corner of the room. The exit door in the next room is closed, but the button to unlock it is down the steps and to the right, on the east wall.

In the first large warehouse room, jump down from the lower catwalk and press the button on the west side. Ride the elevator at the end of the lower catwalk to the upper catwalk and press the button on the pedestal to extend the bridge. Hop down onto some crates behind the catwalk, then proceed west across the bridge through the double doors.

In the second warehouse room, you will see a force field blocking access to some controls on a raised platform. However, you can shoot a pulsating button behind the force field simply by walking into the large room to the left of it. When the force field is deactivated, walk up the steps to the platform and press the green button on the pedestal to start a traveling crane that breaks open the next door. (See Secrets, below.)

Approaching the supply station
After a few elevators you encounter a bridge over a lava pool. When you walk across the bridge, a Berserker will charge at you. Instead of wasting ammunition on him, run back to the start of the bridge and press the green button on the wall. The bridge is lowered into the lava, incinerating the Berserker in a most satisfying manner. (See Secrets, below.)

Next, you reach a flooded room. It looks like some kind of disaster hit, with a hole in a nearby wall, crackling sparks from a shorted power cable, and a sliding double door, half of which is stuck and the other half slides open and closed incessantly. There are a couple of Barracuda Sharks swimming around in there. Eliminate them before you jump in. Clamber onto the floating crates and hop up to a ledge along the wall. From there you can jump into the alcove and activate the wall switch that unlocks the door at the opposite side of the room.

You will eventually reach the first warehouse room again. However, you will be crossing a bridge from here, allowing you to reach the exit to the ../Supply Station/. Just before leaving the Ammo Depot, observe the room with the laser beam barrier across the door. You can hear a Berserker in the room sharpening his spike, but you can't even get a shot at him to get his attention. Above the room is a black crate. For a bit of extra fun, destroy it with a few shots from your blaster to reveal a hole in the floor, then run around the hole until the Berserker sees you, jump down to the lower floor next to the laser barrier and wait for the Berserker to take a run at you. Kibbles and bits! These guys are vicious, but not too smart. You can now enter the room via the hole at the top and collect shotgun shells and first aid kits. Press the red button on the wall to deactivate the lasers and exit.

Approaching the warehouse
When you return from the Supply Station with the four power cubes, use the first one to activate the lift. Riding it to the top brings you only two rooms from the exit to the ../Warehouse/.

Secrets

 * 1) At the start of the map, look up at the ceiling in the far left (southeast) corner.  Shoot the button to reveal a Quad Damage.
 * 2) Behind the force field, there is a button in a darkened area.  Press it to open the floor panel back in the direction from which you came (north).  The chamber under the sliding floor panel contains various ammo items.
 * 3) On the far side of the lava bridge, you can drop down to either the left or right.  This secret leads to a Chain gun (~"Chaingun").
