Chapter 5 - Multiplayer

This section compiles map strategies for Doom 3 multiplayer.

D3DM1 - Tomiko Reactor

Tomiko Reactor is defined, understandably, by a double-floor, circular walkway reactor room. The reactor room houses a couple of the level's most important items. Search the bottom circular catwalk for the rocket launcher resting on a platform attacked to the reactor. Leap carefully to the platform then back to the catwalk. A missed jump sends you plummeting into the darkness below (in other words, instant death).

Drop down the reactor's center to find the berserk power-up and an exit teleporter. Make it quick!

The top of the reactor room holds another price. Walk to the center of the room and look down. You'll see several rotating platforms and a berserk power-up underneath them all. Drop down either on each platform or straight onto the berserk to grab the power-up. A teleporter underneath the berserk sends you back into the map. Now you're ready to unleash some big fist damage on anyone you can find. Don't dive down the reactor when the room is red; there's a red beam coming from the reactor's center and touching it is deadly. Wait until the room is blue and quickly drop to the berserk and get back out.

The plasma gun is positioned in a room containing some sort of piston machine (you may recognize a similar section from the single-player game). If you plan on snagging the plasma gun and walking along the same catwalk, time your advance when the machine is closed. Don't get hit by the piston or the result is instant death. Grab the armor on the other side. Carefully get back to the main path; if you stay to the right you might fall into oblivion.

Find the chain gun on the top of some equipment. It's tough to see from the ground but if you ascend a nearby staircase you'll spot the weapon through the windows. Destroy the windows with a weapon and jump to the chain gun to recover the weapon.

One of the map's key rooms is a multi-exit room just outside the reactor room. It's also the room the berserk teleport transports you to. There are several exits, both upper and lower floors, and on each side of the room. From the berserk spawn spot, the right exits lead back to the reactor room and the upper left exit leads to a cave-like chamber containing armor and health. Expect opponents to move through this chamber frequently moving to and from the reactor room and to the armor in the cave area. If you're hunting here, don't stand too close to the berserk spawn spot or you might be on the receiving end of a rage-filled punch.

D3DM2 - Delta Labs

Delta Labs' most unique feature is the power-up generator. Located in one of the map's more open locations (multiple entrances, wide room, and an upper balcony overlooking the generator), the power-up generator can be used to create a megasphere. The megasphere adds 100 to your current health (up to 200 total health). Activate the console, wait 30 seconds, and pick up your megasphere off of the red spawn pad. Sounds easy enough but during a hectic deathmatch, you're unlikely to have 30 fee seconds to pull off the maneuver completely.

Use the power-up generator to create a megasphere.

As the generator does its job, you may want to hide behind in the left or right corners. There's some cover there but it's well-lit. However, look up and shoot out the light to provide a bit more darkness (the light still flickers). If you enter the generator room and see the countdown, you can almost be 100% positive there's another player hiding somewhere waiting for that megasphere. Fire your weapon into the room's corners to "smoke" the other player out. And of course attempt to steal that coveted megasphere!

The upper balcony of the room offers an excellent vantage point on the generator and any user. Check to see if the generator is active and watch for hopeful opponents to approach the red pad. Or time a drop carefully and grab the megasphere before your opponent can react.

Locate the rocket launcher in one of the labs. It's near some crates along the back wall. Be cautious, though. There's a dark hiding spot to the left of the weapon. Devious players can hide in the darkness here and wait for players to come and snag the powerful projectile weapon. Then again, you could set a trap yourself.
