Tram Rail

For this short ride, all you need to do is fire at the flyers and other trams that try to pull up beside you. Shoot at them when they are moving up and you’ll destroy them even before they get close to you. Focus on the other trams and then the flyers when there is nothing else. Soon enough you’ll reach the Terminal.

Data Processing Terminal

Hop off the tram and make your way forward through the door. Call the lift in the center and then ride it up. When you get off, extend the bridge and go through the only open door. When you enter, quickly destroy the spheres the have electricity flashing around them. They will teleport in some more Stroggs if you don’t. Kill the Strogg atop the stairs and go through the next door. When you enter this large room, quickly destroy the teleporters at the far end and then kill the Stroggs. Run through the next door at the far end. Wait for the center to rise and then spin around.

Head across the bridge and a control panel will lift up. Use it and the power will be activated. Once it is, head back to the large room with the bridge and meet Sledge. Once you do, activate the next bridge on the opposite side and cross. Enter the corridor there and make a left at the curved hallway. When you reach the computer screens, use the panel there to call the lift and you will have to wait a bit for it to arrive. While you are waiting, two large spiderbots will appear and a teleporter will appear down the hallway. Run and destroy it and then work on the Spiders. Use your heavy weapons to take them down and then the lift should arrive across from the control panel you pressed to access it. Hop on with Sledge and ride it up.

Make your way through the open doorway and hang a right. Kill the Stroggs there and continue through the door. Make your way around the curved hallway and kill the few more waiting there. Use the control panel on the right to call the lift and then take it for a ride. When you reach the bottom, make your way forward and up the stairs on the right.

Head back down the stairs and make your way through the door on the left. Follow the red laser and you will come into a large room with a small set of stairs to the right. Go up them and use the control panel there to lower the block in the center and to raise more laser guides. When they are up, make your way to the right and use the lift there. Walk down the corridor once you reach the top and you will find a control panel. You will need to use it to bounce the laser beam around each guide.

Start in the bottom left corner and click it 2 times. For the next one, click it 3 times,1 for the next and finally, 2 for the last one so that the laser is shooting away from you. Head back down the lift and go through the door the laser opened. Hop over the pipes and go to the door at the far end. Go through and make your way around to the right.

Once you do, hop back in the two lifts to exit.

Data Processing Terminal

Once you are in the lift, you will start to ride down and a large bad ass mofo Strogg will start to attack. Keep riding the lift down and give it a few shoots when it smashes the glass. When you reach the bottom, walk to the center and use the control panel there to ride another lift down. Head through the door there and hop on the tram to get to the next tower.

Data Networking Terminal

As you step off of the tram, load up on the ammo and weapons laying around. Walk up the stairs and head through the door there. Step in the lift and go for a long ride up. When it stops, hop off and enter the next room. The lights will go off and some turrets and teleporters will appear. Take them out and the door to the far right will open. Head through there and use the control panel to extend the bridge. Cross it and enter the next room. Take the lift in the center and ride up to the next floor. Destroy the 4 teleporters in the corners and then make your way through the door in the center. Once you go through, continue through the next few doors killing the teleporters and then the Stroggs that made it through. Once you come to the large open room with the teleporter in the middle, wait for the bridge to swing around to you and then cross it. Hop in the teleporter to get to the level right below the roof.

As you appear through the teleporter, the guardian will be at the glass in front of you. Make your way to the left and jump up the destroyed ramp there and head to the left. Cross the bridge there and make a right to enter the large room. Destroy the teleporters in there and the Stroggs and continue through the next door.

When it stops, get off and make your way down the corridor to the right. Hop in the next lift and ride it to the roof. Head out the door there and now you will have to face off against the Guardian. The guardian is a big bad mofo that has been chasing you for the past little while. When you reach the roof, he will be flying about on his little rocket pack. To defeat him, you simply need to whittle away his life until it’s all gone. He has plenty of attacks, such as rockets, swooping at you and using his jets to try and fry you.
