Keep moving forwards until you reach the elevator. There, it will turn out that it is not working, and you have to turn on the emergency power supply. Go back a bit and approach the big, red gate, which you have to kick open.
Approach the turbine's mechanism and try to turn it on. It turn out that The Swarm has sealed the turbine, and you must first remove the slurry which jams it. After you bring back the power you have to return to the elevator, but several enemies will stand in your way. Cut through them, approach the elevator and try to turn it on. It will still refuse to activate and you will have to split up your team again.
The difference being, that if you choose the Generators, you will go via the lower route, and if you pick the Operation Deck, you will go via the higher route. Those above will mostly support the ones below during the fight by the generators, and those responsible for the generators will have to aid the others in the sections between the generators, when they are e.g. pinned down by a turret.
When both generators are turned on, the team will again be complete, and you will be able to return to the elevator. The elevator will finally work, but it will not go very far, and will soon be jammed.
In the next room, another fight with a Carrier awaits you. The Juvies, which will start emerging from the destroyed pods, will be a problem, but as long as you keep your distance, you should be able to defeat the Carrier with relative ease. Remember to attack his chest, whenever it is exposed.
When you proceed, a passage through two turbines will be ahead of you. You have to pull the lever next to a turbine and run through the middle when it stops. In the next room, a fight with a more powerful representative of The Swarm will be waiting for you, but it will not be anything that you have not previously encountered.
Keep advancing, and you will find a room where Gears were trapped several years earlier. Amongst the bodies you can find one collectible dog tag. In the room with chains you will once again be swarmed by enemies. After you repel them all, keep moving forwards and turn left before the passage through a red doorway. There, you should find another item for your collection.
In the next room there will be even more chains and enemies, and additionally, a Scion. It is best to kill the weaker enemies first, and take care of the tougher one later. When you defeat it keep moving forwards, and your team will split up after a moment.
After you climb the first ladder, you will be immediately attacked by a Snatcher and several Drones. Of course the Snatcher will appear at the end, allowing you to e.g. pick up a bow from one of the enemies.
When you slaughter all of the foes, go back inside and follow the corridor until a cutscene which ends the act appears.
