Alpha Lab Sector 4

As you step out of the airlock, move forward and got to the left. Go through the door there and you will enter a large room with a glass wall chamber with a scientist in it. He will ask you to open the door by using the panel. You can either open the door or fry him by using the panel but opening the door will get you another PDA. Open the door and then head through the door on the right to ride a lift down to meet up with him at his office. Listen to him talk and grab the PDA off the desk. Also notice that there is a glass storage cabinet in there. To open it, press the button on the blue screen to the left of the cabinet and to the right of the scientist. That will open the cabinet and give you loads of ammo and the chaingun as well. When he’s done chit chatting, exit his office and head to the right. Go through the large door there and there will be an imp in front of you and two z-secs on the walkway across the second floor. Kill them all and then a load of trites will enter the area.



Kill them and head up the stairs on the left side and make your way along the catwalk to come to two doors. One on the left and one going straight. Kill the trites and z-secs that appear and go through the door on the left. Follow the hallway around the corner and you’ll hear a voice saying “come on, follow me”. When you reach the end of the hall, you will hear another voice say “they took my baby”. Head back out and go through the door that is on the left now. Once you are through, Sarge will tell you that you have two choices to take now. One is the EFR system that is more dangerous but lit and the other is the service bridge that is safer but dark. Lets go for the more dangerous one. As you exit the second door, activate the monitor and click on the EFR choice. Also here you will get another PDA, this time of Henry Nelson. When you activate the EFR, it will move a platform out to the left of you. Use sprint and run and jump across to the platform and then across to the next ledge.



From there, there will be a platform in the center of the room that spins around the center. Jump across to it and let it move one turn to the right. Jump off it to the small room there and go through the door. When you enter, kill the two maggots that spawn and activate the ERF Processing on the monitor. When you do, leave the room and jump back to the moving platform. Let it move one more turn and jump across to the next ledge. You need to use sprint and you need to wait until the absolute last second to jump to make it. Go through the door and take out the z-secs there and in the room to the left. When they are all toast and you have all the goodies you need from the storage room, head back to where you entered and jump on the platform that is moving to the left slowly. Stay on the front right corner and let the platform move until it moves down to another door.



Walk off the platform and go through. Take out the imp and trite there and go down the stairs to reach a terminal that has a control panel that allows you to “initiate magnetic field charge”. Press it and then head back up the stairs and go to the right. Now you will need to jump across the two platforms as the yellow cylinders move around. Make the one jump and then kill the imps and make the second jump. Once you reach the other side, go through the door and hop on the next moving platform moving left. Ride it until it reaches the far left and hop off to the open corridor there. Kill the z-secs as you follow the hallway around to the right and up the stairs. Continue to follow the hallway around and when you go down the set of stairs, use the med station if you need it since you will be heading into a boss battle now. Go through the green light door and you will be squaring off against the Vagary.



The Vagary isn’t all that tough as long as you keep moving. The lady spider will toss rocks and grates at you with her mind and if you stop to admire the scenery, you will get nailed by them. Strafe around either far from her and toss grenades, or strafe close to her and pound her with your shotgun. When she does throw an object at you, use the sprint button to move out of the way faster. Keep repeating that pattern while unloading shells into her and she will drop in no time flat.

When you reach the end of the vent shaft, kill the zombie on the right and head down the ladder to go back out to the mars surface. When you hit the ground, turn around and take out the trites and head to the far left grabbing as many oxygen tanks as you can. You will come to a lift that will take you back inside the base. Press the button to call it and fight off the trites as it comes down. Hop on when it does and enter the base. Take out the z-secs and imps that are in the next room. Head to the right and take out the three caco’s that appear here. Make your way to the left and you will come to a couple of shelves with crates and imps and a locked red door to the right side of the service tunnel. Go through the open door on the left side and there will be two chainsaw zombies that come out from each side to say hi.



Kill them and the few other zombies that enter and grab the PDA of the floor. Once you have it, head over to the red locked door that was on the right and use the PDA on the control panel. Enter the hallway and it will turn black and light up red off and on. Kill the two zombies to the right and straight ahead. Continue down the hall and to the left will be a door that is locked and to the right an elevator low on power. When you check the elevator, a pinkie will rush out and the previous locked door will be open now. Go through to the right and kill the imp and wraith and around the corner will be some lava breaking through the floor. Kill the caco there and head around the right corner to the ladder there.



When you reach the top, you will get an objective to reach the control room and unlock the maintenance doors. Head up the stairs and there will be a control panel there that you need a PDA to operate. Head through the door on the left and follow the hallway to the right. Kill the imps, wraiths and pinky’s and go through the next door on the right. Grab the PDA on the ground next to the body and operate the control panel there to call the platform over to you. Stand on the 1 to the right and hop on the platform when it arrives. Turn the platform to the left and move forward. When you reach the end, turn right and move forward twice. Kill the z-sec that appears on the left and raise the platform up.



Head into the door on the left and follow the corridor to the next door. Go through and start to cross the bridge and an imp will appear. Take him out and continue through the door on the other side. Kill the z-sec on the right and the imp that will appear near the door. Continue up the left side of the room and kill the chainsaw zombie in the control room. Once he is dead, activate the control panel on the monitor to open the maintenance exit. Head back to the platform you were riding on and click the “move to station three – lift exit” button to move to the maintenance door.



Hop off the platform when it reaches it and kill the caco that appears. Head through the door and use the med station if needed. Make your way to the end of the hall and the floor will drop down. Grab the berserker pack there and start punching all the zombies that fill the area. When they are all dead, head for the yellow striped stairs and jump up to the door atop of them. Go through and kill the chainsaw zombie there and head for the airlock at the end of the hallway. Go through and run straight forward and ignore the caco’s that appear. Go up the small staircase on the left and head for the airlock there.
