Enter the area with the reactor core and take the elevator down. A higher level android awaits you at the bottom, so be prepared to fight! Remember, don't use an EMP Mine on this kind of android, it doesn't work! Your best bet is to use the Bolt Gun as each android approaches. Keep it aimed at the head to ensure an instant kill. The noise will attract the other androids, so be ready to take them out one by one.

And here we go. The entire place is a nest made by the Alien. Remember all those disappearances you've been hearing about? Yup, they're all down here being used as hosts. Grab your Flamethrower and head over to the main room to save.

Follow the only path available. As you go down the hallway, watch out for the bud like forms on the ground. A Facehugger may crawl out of one, so be prepared to incinerate when it starts chasing you. Enable the conduit interface, then disengage the locking mechanism in the middle, and finally activate the Alpha Conduit.

Enter back into the main area where you started. Head down the hall, but don't go too far down. There is a small hole on the right wall that you can take to the other hallway. Things to keep in mind. If you see a closed alien bud on the ground, blast it with fire to take care of it before a Facehugger can get out.

In the next hallway, use your Motion Detector to guide you down the right path. When the Alien is nowhere in sight, save at the save station. You need to repeat the same process here with the beta conduit as you did with the alpha conduit, but of course, the power is out.
