Objective: Find the entrance to the processing plant, and then locate the power station.
Before you shoot the guards in front of you, turn around and look for the heath packs behind you. Then proceed out into the hallway and turn right, through the door.
Kill the guards and Gunners and enter the room with the large lava pit. There is a tram to the left but it can only be used from the other side of the pit so leave this area and return the way you came.
Walk past the way you came in and press the button to open up the vertical red chute. Jump in and kill the Barracuda Sharks while in the water. Jump out into the red tube and destroy the Flyer.
Look down over the lava pit and kill the Strogg soldier guarding the button. Drop down and hit the button to lower the walkway over the lava - but hurry - it will lift back up momentarily. Once across, kill the Gunner and push down the lever to drain the lava pool.
Hop down and press the green button on the wall, which will open up another tube to crawl into. Go up the small set of stairs to reach the platform. This will rise you to the tube. Enter it, and climb up the long ladder.
As you reach the top, one or two new Strogg are after your hide - Brains! Kill them fast an collect the power-ups on the floor. Exit the hallway and destroy the Gladiator protecting the green button.
Push the green button and head back to the room with the Brains in it. There are three moving platforms you can access, but the middle one has some Jacket Armor at the top of it. Drop down into this room and collect all the health and power-ups you need.
The section of the wall opposite where you jumped down has a different color light in the middle. Walk up to this panel and it will automatically open up to a secret area with armor, rockets, and bullets.
Leave this area and enter the sliding door to the right. Cross the bridge but expect two Beserkers to cut you off. Be careful not to get hit by one of them or youΓÇÖll end up in the pool of lava. Hit the button on the wall to let you out of this room. You are now near the beginning of the level again.
The lasers are now de-activated. Turn to the right to collect the Stimpacks on the walkway over the water. Drop in once youΓÇÖve killed the Beserker and look for a yellow-shaded dry area under the walkway (opposite the waterfalls). Enter this small compartment to uncover a secret area with a Railgun!
Enter up the ramp and continue along the walkway again toward the waterfall. Run and jump on top of the waterfall, and go behind to uncover a secret level!
Note: this secret level, called “Sudden Death”, is more of a timed, 30-second free-for-all bonus area with lots of power-ups but no enemies or secrets…so there is no walkthrough. When the time is up, you’ll be back on the walkway overlooking the waterfall again.
Head back inside and kill the Parasite waiting for you. Now walk toward the lava pit you couldnΓÇÖt get across from the beginning of the level and there will be a grate with a hole big enough to drop through. There may or may not be Gladiator on the other side of the partial lava pit.
Fall through the grate in the floor and collect the ammo. Step on the platform to reach the other side of the lava pit (now that was easy, huh?). And step back to blow up the gray explosive box. There is a Quad Damage in there.
Continue down this hallway toward the two health packs and exit this level through the double doors to the Processing Plant (2).
After returning from the processing plant, walk straight into the room with the lasers on the floor and step on the moving square platforms. Once youΓÇÖre on the first one, wait until it takes you closer to the second, then jump across and onto the other side. Kill the guard and exit the room.
Open the door and tackle the two Icaruses hovering above you and then proceed down the stairs. Kill the Enforcer and Flyer and continue along to the red buttresses on the wall near the exit door. Shoot the yellow light and walk inside the room containing lots of health packs and ammunition. Exit the door at the end to leave Unit 5 behind. You’ve got bigger fish to fry now, soldier…the Big Gun unit awaits.
Unit 5 Level 1: Secrets
Secret: 1 - Press the middle panel to open up a secret area with some goodies in there for you.
Secret: 2 - Once outside, jump down off the walkway into the water and youΓÇÖll find a Railgun underneath, in the wall!
Secret: 3 - Jump off the end of the walkway into the waterfall…and over…and you’ll find a bonus level chock full of power-ups.
Secret: 4 - Fall through the grate in the floor and then shoot the explosive boxes to get out. One of them will also uncover a Quad Damage.
Secret: 5 - Shoot at the red light in the ceiling under the doorway and a panel in the wall will open up uncovering an Adrenaline pack.
