Walkthrough:

Note: You can run as much as you want in this mission, until you get the objective Overload Beta Core. In any case, you have to be mindful of aggressive Synthetics as well as a Facehugger before you get said objective.

You start the mission while still in the elevator. Once you reach the bottom of Apollo Core, go through the only door and the second door just behind it. After finishing a conversation, you will be given the objective Investigate the Central Reactor. Turn left and interact with the electrical junction to power up the tram systems; turn around and interact with the generator a bit ahead to move the tram that was previously blocking your way forward. After the tram has finished moving, continue through the newly created opening and save your game at the save station to the right. Go through the door to your right into a short corridor, and through another door at its end.

You will enter another corridor with several security cameras, which you can either sneak past or deactivate by using the rewire panel in the first room to the right. There will also be a Synthetic that you can either kill or avoid as well. Regardless of your choice, continue going left and picking up the Ion Torch on the desk in the middle of the first room to the left. Continue along the corridor until you reach a vent that is blocked by a metal plate. Use your new Ion Torch to cut it open, then climb inside. Follow the vent all the way through the end, then exit into a room with another save station; save your game.

Leave the room and enter the Workshop, where you will encounter at least one, maybe two Synthetics. Wait for the right opportunity, then kill one or both of them. While walking through the Workshop, your objective will change to Find a Way Out of the Engineering Workshop. In order to do so, you need to activate three different electrical junctions, one located on a small ramp leading to a door, and the other two in different corners of the Workshop floor. Finally, interact with the generator in the room to power up a winch, which lifts up a vehicle parked in the middle of the room, revealing a hole in the floor for you to drop in.

Drop down into a corridor which turns into a vent; follow it until you reach a ladder. Climb the ladder, then exit the vent into another corridor. Approach the door in front of you and use the ion torch to cut the panel. Use the lever to open the door, but do not go through it; this is merely to save you some time later on. Turn around and follow the corridor until you reach another save station. Save your game, then go through the door next to the save station. You enter another corridor, and your objective will (again) become Investigate the Central Reactor. You will witness two Synthetics exiting the corridor into a room ahead of you, dropping a shutter behind them. Approach the shutter to have your objective changed to Unlock the Shutter.

Turn around and go through the only door on the left, then through another door on the left into another room. Continue straight until you can enter another room on your left. This room will most likely contain an Industrial Synthetic, which you should dispose of with a Pipe Bomb or a combination of hit-and-run with your Maintenance Jack. After the Synthetic is gone, pick up the Bolt Gun from the table, and collect all Bolt Gun ammo you can find. Access the computer terminal and read the first entry in the 'Personal' folder to learn the code to unlock the shutter (6832). Browse to the 'Utility' folder and use the code to get access to the Security Shutters entry; select it, then exit the terminal. Your objective will change to Get to the Reactor.

Since you are now a proud owner of the Bolt Gun, as soon as you fire it for the first time, you will earn:

Return to the doorway which was previously blocked by the shutter. Continue straight, then left, to reach a corridor leading to an elevator. Press the button to call the elevator, then go inside and press another button to be taken to Central Reactor. Once you arrive, continue straight through a doorway into a corridor that leads to a ladder. Pick up the conveniently placed Shotgun and Revolver at the base of the ladder, then climb up. Once at the top, save your game at the save station before continuing through the doorway on your left and another door to reach the reactor area. Before you enter the elevator to your left, look down to ensure that the Industrial Synthetic to your left moves away from the point at which you would exit the elevator. Your objective will change to Descend to Base of Reactor. Equip the Bolt Gun, then press the button inside the elevator to take the ride down.

Make your way to the objective marker, by either passing the reactor core on the left or the right side. There will be four Industrial Synthetics in the area, which you should kill with fully charged Bolt Gun head shots. Once they are taken care of, collect all the Bolt Gun ammo that you can find in the area, then continue through a door to reach corridor. Use the elevator at its end to be taken to Central Reactor Maintenance. Much to Ripley's horror, you will reach the Alien hive.

Whatever you do, don't forget to pick up the Flamethrower on the desk to your left, reload it if necessary, and equip it immediately. After a conversation with Ricardo, your objective will become Destroy the Nest. Continue straight to reach a save station. Save the game before continuing through a red door on your left. You will be given the objective Overload Alpha Core. Keep going slowly around two corners towards your objective marker. Just as you pass the last corner, you will hear a shriek from a Facehugger. Back off a bit and roast the filthy Alien spawn with your Flamethrower. Note: If you have Shotgun ammo in excess, kill the Facehugger with the Shotgun instead, to save Flamethrower fuel.

Destroy the two closed Alien eggs in the area with either the Shotgun or the Flamethrower, then enable the conduit interface by interacting with the console in the room. Whenever you spot closed Alien eggs from now on, torch them with your Flamethrower to avoid more Facehuggers bothering you. Approach the pillar in the middle of the room and pull the lever to disengage the locking mechanism. Before you continue, return to the save station and save your game once more. Go back to the pillar and pull another lever to activate the alpha conduit. Immediately enter the next locker you can find. Your objective will change to Overload Beta Core, and the Alien will walk past your hiding place to investigate the noise. Wait until it is gone before you leave the locker and go back to the room with the save station. Save your game once more if you have the chance, then continue straight and left into a corridor with a Secondary Coolant Storage sign above it.

Keep to your right and locate a small vent or tunnel, crouch inside and continue straight. Leave the tunnel and turn right, then around two corners. You will be attacked by another Facehugger along the way. Wait for the shriek and deal with it the same way you did before. It is highly likely that the Alien will drop down a ceiling vent to investigate the noise, so be ready to use your Flamethrower to have it retreat. Once it is gone, hide in another locker and wait for it to return and leave once more. Continue on the left until you reach Beta Core Conduit. An Alien will drop down in front of you; either scare it away or wait for it to leave before you use the save station at the right hand side of the room. Note that there might be more than one Alien in the area now, so don't feel too safe once one has just left. Approach the console to your left to update your objective to Redirect Power to the Central Core.

Continue into the corridor leading south. Keep to your left and locate yet another tunnel. Follow it to the end to reach a generator. Interact with it to restore power and have the objective change again to Overload Beta Core, then crouch back into the tunnel. Make you way to the room with the save station. Try to save the game before interacting with anything, and once more after you are finished. Once you have done so, follow the same three steps like at the alpha conduit to activate the beta conduit, i.e. interacting with the console (this time in a small room to the right) and the two levers at the pillar. Once you have successfully activated the beta conduit, make your way back to the elevator in which you entered the hive. It is highly likely that you will be attacked by another Facehugger just after passing the save station, and it is guaranteed that yet another Facehugger will come at you once you crouch through the tunnel.

Once you reach the elevator, press the button to return to Central Reactor Maintenance. At this point, if you managed to finish the level without dying, you will earn:

Note: From now on, you can run as much as you want in this mission, again being mindful of aggressive Synthetics.

As soon as you leave the elevator, get your Bolt Gun ready. Once you reach the reactor core area, your objective will change to both Overload Alpha Core and Overload Beta Core. Even though you killed four Industrial Synthetics previously, the area will be swarming with four more soon enough. Kill all of them with charged Bolt Gun headshots. If you run out of ammo, run away from the Synthetics around the area to pick up all ammo you can find. Once all of them are dealt with, follow your map marker to reach a console. Pull the lever to start the overload. Follow your map marker to another terminal and play a short minigame to deactivate the core limiter. Follow the marker again to another terminal and another minigame which will deactivate the protective relay.

Keep following your map marker to do the same steps for the beta core, i.e. pulling a lever and playing two minigames at different consoles. Once you have done so, your objective will become Redirect Power to the Central Core. Four more Industrial Synthetics will show up, but it will be easy to outrun them, so do not waste ammo. Locate yet another console close to the corridor leading to elevator to Central Reactor Maintenance, and pull the lever. Your objective will change again to become Initiate Purge from Reactor Control. Run past the Synthetics to the opposite side of the core and go through a door leading to the Emergency Exit. The door at the end of the corridor is locked, so enter the vent on the left. Follow it to the end, climbing a ladder in between, until you drop down into the Control Room. Interact with the two consoles on the left and the right side to play a minigame each and initialize the emergency purge sequence.

By this time, you should have completed 10 different minigames, thus earning you:

Press the button in the the middle of the console to purge the nest. After a cutscene and a conversation, leave the room through the door leading to the Transit Station. Your objective will become Return to Ricardo. Keep going straight, through a door and up some stairs to get the the Transit Station. Save your game at the save station. After another conversation with Ricardo, your objective will change to Go to the San Cristobal Medical Facility. Press the button next to Towerlink 02 to call the transit. Enter it once it arrives to be taken to SCIMED Tower, updating your objective to Get to Sevastopol SCI/MED Tower and ending the mission.

After the mission, you will earn:
