Firstly let me begin by thanking Time_Rift as he is the person who showed me the entire map.

Notice: There appears to be 2 (or more) versions of this map. It appears to choose at the start from a set of variable differences. I will name as many as these differences through out this walkthrough.

Thegame2008_1: Begin by turning the black valve near the door.  Next go through the first door you see, turn left (you should see a smoking sign) go through that door, go to the open door turn left again and there will be a double door with 2 buttons either side. Both must be pressed for the doors to open. Now you should be in a room with water in the center, go past the water till you get to a control panel (see screenshot). Press the middle screen and the red light will go off. Wait for a sound alarm to begin (takes about 30 seconds literally) and then press another button to the left of the control panel.

Now get a team mate to boost you up the ladders opposite the control panel to the right. Hit the panel at the top of these ladders. Now get down from the ladder, go back to the control panel and press the final red button. This will initiate red lasers and cause a screen black out.

Now you must get back up to the top where the panel is by using the red railings and teams mates. Once there hit the panel once again. This will cause the red lasers to shut down. Go back down and look for a vent to the right when u fall down. Go through the vent and break the glass. Go left and  hit the button with two arrows facing each other. Now grab some cells and break the vent to the right and follow it.

Difference 1: this route is sometimes unavailable, if the vent is closed this way, go this other way: 3-4 men required, get a boost into the vent  in the roof. Once you get on the other side of the door, hit the switch to open it and let other people through. (see screenshots)

Now there is an Ice floor with two electric wires hung down that will instant kill you if you touch them (see screenshot below).

Once past them there is a door with some water, be aware this water is electrified and will hurt you (see pic below).

This picture shows electric:

Bunny hop the randomly placed objects until you get to this electric.

Difference 2: Sometimes this will be harder as it will have a different layout involving more jumps.

Once there look for a light switch really close to it, when you see it press use on it. Now go to the room with the radation picture.

This requires approximately 3 people to do. Get to the top and go right (in respective correlation to my picture). Follow it round to you see a no smoking sign then look to your right and you should see a broken panel, fix it by hitting it.

Fall down into the water. Go back out the doorway and around the corner to another doorway, go up the stairs and follow the way around until you reach an evelator door (see first picture below). Press the elevator button to open the doorway to the shaft. Get a boost to the second floor (ladder to the left of the doorway in) and on the second floor press the up directional button a few times to raise the elevator. Now jump back down and go underneath the elevator. Get a boost inside the elevator (see second picture below), press the button a few times (third picture below) then head on up to the third floor (fourth picture below) (a boost is no longer required cause the elevator is raised).

Once on the third floor go straight then turn left where you will see two voice panels, get two people to press at same time. This will lead you to a portal room.

Battery 1: Now go back outside the portal room, turn left and follow the corridor all the way round till you come to a doorway with no door. Once you walk in there will be a battery placed on your right.

Get it and take it back to the portal room, inside go to the very back of the room and get a person to boost you and jump. (The battery would be in my screenshot below but i already took it).

Difference 3: Sometimes there will be a door. If this is the case go back outside turn left and find a vent. Break it and take the first left, follow it.

Battery 2: Once you have taken the battery back return to this same room. Go through the vent take a first left follow round try not to fall (else 2 people required) and take the first right out of the vents. This will lead you to a room that is on fire.

Difference 4: It might not be on fire

You will need a boost either way and the battery is behind the objects.

Now you have that battery get out by going back through the vents (requires boost if on fire). Take this battery back to the portal room and repeat what you did with battery 1.

Battery 3: The third is by far the hardest. From the portal room walk straight forward to the vent where you will see a security door. This requires 3 people.

Note: the electrical box at the end explodes if hit. Take care

Here are the instructions: the right valve opens the first second door and the second second and the left opens the first first door and the third second door. The second left valve (as you come through the door) opens the first first door and the third second door and the second right valve opens the second first door (therefore first right valve and second left valve must be used together). The third left valve (as you come through the door) opens the first and second second doors. The third right valve opens the first third door. SOOOOO LOL, put more simply...

(The first 1 2 or 3 = the order of the doors - The second 1 or 2 = the door itself):

Valves: ->Opens-> Doors:

1st Left              1 1 & 3 2

1st Right            1 2 & 2 2

2nd Left            1 1 & 3 2

2nd Right              2 1

3rd Left              1 2 & 2 2

3rd Right                3 1

Directional instructions:

Step 1: player A holds first left valve and player B holds first right valve, player C goes through to part 2.

Step 2: Player C holds 2nd left valve and player A goes to part 2.

Step 3: Player A then holds the second right valve. Player B continues to hold the first right valve. Player C goes to part 3.

Step 4: Player C holds the 3rd left valve and player A holds the second  left valve. Player B joins player A at part 2.

Step 5: Player C holds 3rd left valve again whilst player A or B holds second right valve. One of the players advance to part 3 (player A in this case).

Reminder: Player A and C are at part 3 and player B is at part 2.

Step 6: Player A holds 3rd right valve and player B holds 2nd left valve. Player C advances to battery and gets back.

Step 7: Player B holds 2nd right valve whilst player A holds 3rd left. Player C goes to part 2.

Step 8: Player A holds 3rd left and player B holds 2nd left. Player C goes to back to part 1.

The other 2 players trapped type kill in console.

Player C takes the battery to the portal room and repeat the battery process.

Once all batteries are in place the portal will start.

Go through the teleport, jump off the platform and look for a small vent behind 3 barrels. Follow this vent round till you come to a button and a hole. One person press the button then another JUMP down the hole (does not work if you do not jump). Once down the hole you will be floating, locate a platform that stretches slightly out and leads somewhere (not the grated one) then tell the player at the button to press it once more, this will stop the floating. Now follow the platform to the edge (be careful) and tell the player to once again press the button. Walk off the ledge and go up the hole, follow the vent out.

Difference 5: There may be a black wall blocking the vent which means you drop down, go under then over it. Makes it quite a lot harder.

You will need a team mate to open both the door via both switches.

Make your way through the door to the right on my screenshot above and then all the way to the top with boosts in the necessary places. Once on the top platform get a team mate to use the valve. Also places 1-2 barrels on the grate below as you are required to jump on them to break it.

Once you land on the barrel you will be stood on it above the green acid. The barrel will move once the valve below is pressed by a team mate (see screenshot below) and you must walk with the barrel to survive.

Once you follow the barrel round you should come to a vent with a fixable panel inside. Hit this panel to fix it (screenshot below).

Now go back and get onto the barrel. Go to the other side of the acid the way you came and get a team mate to boost you up to the vent on the right. Fix the panel.

Difference 6: There may be grates to boost over aswell.

You must then go through a vent. Here is the video for directions: Vent video. After that go straight and to the right. You should come to a hole in the roof. Get a team mate to boost you up so you can get the barrel down.

Now push this barrel around the corner into the fuel machine and press the button so that it explodes.

Next there should be a ladder, go up it and follow the obvious way around to the last two switches. You have now completed thegame2008 part 1.

P.S The secret chicken is up the ladders ;).
