After getting out of your hibernation chamber, go over to the door and press the Open button. Head through and read the logbook on the screen when it appears - this gives you the passcode of 31415. Go over to the next door and enter this code, then press the Open button. Go through to find that the next door panel is broken. Crawl between the crates, jump over another crate when instructed, then press the Open button on the next door panel and continue through.
Turn left at the fork, then take the first right and enter an office on the left. Read the message and logbook on the screen here. There is another office in this short corridor, but it contains nothing useful. Return to the previous corridor and continue to the right.
Take the first left and enter an office on the right. Read the logbook and the message in here for a clue about a hidden security card. The other room in this corridor doesn't contain anything useful. Return to the previous corridor and turn back to the right. Follow this past the original fork and around to the left. Pick up the red cable and use it to connect the 2 unused connectors in the open panel on the wall. Now open the door on the left. Find the panel that says HUB A-27 on the wall in this room. Open the panel and pick up the card from behind it.
Return to the corridor and turn right. Go all the way around, over some red boxes, until you find a screen that says "System Offline". Behind it you will find door E-7. Use your card on the panel here, then press the Open button. Head through the door.
Turn left in the large open area. Jump over the crates and explore around to the left to find a memory disk on the ground - pick this up. Continue around the corridor and pick up a bolt from a fallen red cabinet. Don't walk into the anomaly in front of you or you will die. Instead throw the bolt at it to see its effect. Pick the bolt back up again. You can use this to find a safe passage through the anomaly. Start on the right, and get to where you can pick up more metallic objects. Throw these to gradually find your way through to the other side.
Ignore the side passage to the left with the smaller anomaly, then press the Open button on the door ahead to the right. Go through to the second room here and pick up the switch from the shelf, inserting it into the device on the bench. Now flip the switch so the indicator is green. Go back to the first room and pick up the spare switch, inserting it right here, then flip both switches to turn the indicator green. Now you can press the Open button on the door in the second room and go through.
Read the message and logbook in here. Insert your memory disk into the top of this device and read the notes (although they are damaged). Search the double cupboard and pick up another switch. Insert it on the desk here, then flip it to turn the indicator green. Press the Open button on the panel and go through the next door. Head along the corridor and turn right at the fork, then press Open on the next door panel.
Turn left and press the Open button for door E-4. The door panel will be disabled now and air will rush in. Head back against the flow of air and into a small corridor on the right. The door will automatically close behind you and the room will re-pressurize. Open the next door and head through.
Follow the corridor left, then turn right and open door E-14 at the end. Open a window on the right to see part of the planet outside. Continue through this damaged room and open door E-15 to continue. Jump over some red crates blocking the next door, and head through door E-17 to the left as it opens and closes automatically.
In the next room turn right and press the Open button for door E-18, then head through. An alarm will sound and you will see a message about needing to replace air filters. Turn around and open the panel that says HUB A-40. Remove the 2 used air filters from in here; you can drop them on the ground.
Go back through door E-18 and find an Energy Redirection panel in the other part of this room. You need to click on the tiles to link the battery to the other door. The following diagram shows the correct path for linking to door E-18.
This diagram shows the correct path for linking to door E-34:
Now press the Open button for door E-34 and head through. Continue left, right, right, and go through the first door on the left. Read the notifications, logbook and message here, then search the cabinets to find a filter and a cable. Leave the room and turn left. Go all the way to the end, then go left and through a door. Use your cable on the open panel on the left, then open the next door. Read the logbook, messages and notifications in this room. Search the cabinets to find another filter. Go back to the Energy Redirection panel and change it back to the first configuration. Open door E-18 and insert your two new filters. Watch the display on the opposite wall to see the carbon dioxide levels return to normal. Door E-19 will open so you can go through.
Press the Open button on the door to the left, then go through here and around the corner. Jump over a crate, then open and go through the door on the left. Read the logbook and messages here, then go back out, turn left, and crawl between the crates. Close the door where you can see the flame ahead, then wait for a while before opening it - the flame should have been extinguished but there is still gas leaking.
Run past and open the next door, then go through, turn around and close it again. Keep crouching through this area to stay beneath the level of the smoke. Go straight at the intersection, and you will see a panel that is Out of Order on the right wall. Turn left, right and left, then close the door ahead. Turn around and follow the corridor to the right. Go through the door near Hub C-45 so you are on the other side, then close it. Wait here for a few seconds and the flame should have been extinguished. Open the door again, and go straight ahead, past the gas. Open the door, go through, turn around and close it again, then step forward into the room.
Head around to the left and look at the Circuit Bypass panel. Click on the symbols to complete the circuit from left to right (4, 2, 5, 1, 3). Now open door E-44 to your left. Watch out for the rotating laser in the next room, making your way to the right and into a smaller room to the right. Read the messages, logbook and notifications here. The other room off the side of this one has nothing of value, so return to the corridor and use the switch directly opposite to disable the laser. Now head right, then left. Ignore the side corridor and jump over some red crates ahead.
Turn right, then enter the male toilet to the right. Open the closed toilet and take the card from inside. Return out to the corridor and ignore the female toilet, turning left and going straight along the corridor. Open the closed door ahead, then turn left and explore a small room on the left to read some more messages. Back in the corridor, turn left and open door E-46.
Go through to find the laser you disabled earlier. Turn right and crawl through the opening of door E-41. Use your card on the slot here, then open and go through door S-10.
Head around to the left to find a screen, and read the logbook and messages. Now go up using the nearby lift platform to reach a series of reactors with control panels. You need to adjust the wavelength and amplitude of the signals displayed here to turn all the screens green. The electrical discharges will stop once all frequencies have been adjusted correctly.
Go back down to the ground level and go and open door S-11, then go through and open door E-50.
Open door E-51, then go through. Turn left at the end and go through an open door on the right. Turn left again and open another door (the station will shake at this point). In the small room here, open the door on the right and go through to read the messages and notifications. Go back and open the other door. Explore the area to the left and read the messages and logbook. Go back out and open the next door - there will be an explosion. Retreat and close the door, then look at the Energy Redirection panel on the left wall. Adjust it to take this path:
Go back into the room with the gas and use the panel on the side wall to activate the manual exhaust procedure. Once the gas has cleared, you can open the other door in this room and head through. Go straight ahead through another door. Turn right and open door E-59, then find a Diagnostic panel to run a diagnostic scan, which shows you are contaminated. Open the door to the small side room and use the Decontamination panel here. Go back and use the Diagnostic panel again. Now you can open door E-60.
Enter the small room on the left, avoiding the anomaly ahead. Read the logbook and messages to get most of an upcoming door code. Search the cabinets to get some metal items, then head back out to the anomaly corridor. Throw the metal objects to find a safe path around to the left - start on the right, then get to where you can jump on the crates to get past the anomaly. Go through the first open door, then open the second one with code 63274. Head through the door.
Go around the curved corridor and through 2 doors. Turn left and push the button to get a can (repeat to get a second one). Continue straight, then take the second right corridor. Jump over the crates near the end, then turn right and go through a safe anomaly, then turn left and go through the open door. Turn right here and go and open door E-67. Inside you will find a tripod connected to 2 large orange generators - the laser and a fuse are missing at the moment.
Go back through the door and then turn left to go through a smaller open door. Enter the room straight ahead and read the messages and logbook. Take the laser from the table here. Backtrack and turn left. Turn right at the intersection and explore a small room here, reading the logbook, messages and notifications. Search the cabinet in this room to get a fuse.
Head back to the room with the tripod. Put the laser on the tripod and the fuse in its slot on the generator. Turn on both generators, then use the panel to activate the laser. When it is finished, go and push on the round segment of the door until it falls through. Crawl through the opening. Go straight ahead through the large door, then continue through door S-27.
Jump up over the crates on the right. Head to the far corner, then make your way through the middle of the room, then turn right on to the white crates. Make your way around first to the left then to the far right corner. Open door S-26 and head through. Turn right and use the Circuit Bypass panel. Click on the symbols to complete the circuit from left to right (2 bottom, 5 top, 1 bottom, 3 bottom, 3 top). Turn left and open door E-64, then go through.
Open door E-63 and continue ahead. Turn left and open door E-71, then air will rush in. Follow the direction of the air and go through door E-72, then go through door E-73 to the left. After this door closes, the pressure will return to normal.
Continue through door E-74, then ignore the first turn to the right and turn right at the end. Go through a small door on the left and straight ahead into another room. Read the logbook and messages. Turn and leave this room, then turn left and head along the corridor, jumping over some red boxes and turning right. Go around some large crates, then find door E-80 - this is locked and requires the missing card to get through. Backtrack and go through the open door E-79, then into a greenhouse. Search the floor amongst the red crates here and pick up the hacking card. Return to door E-80 and insert this. Now turn right and look at the Local Controls panel. Click on each of the 4 sectors when the markers are within them, then open the door and go through.
Turn left and jump over the box blocking the door. Turn left and open the next door, then go left twice. Read the messages and notifications here, then go through another room and pull the cable out from the wall on the left. Now pull out the fan and crawl into the duct. Go all the way through and push out the fan on the other end, then exit the duct. Turn left, then explore a room to the right, reading the logbook and messages. Go back past the duct and open the small door straight down the corridor.
Enter the room on the right and read the logbook. Take the detonator from the desk to the right, and the explosive from the cabinet behind you. Leave this room and continue straight ahead. Turn right and head down the corridor with lightning bursts (hopefully avoiding getting killed). Open door E-84 and go through, then crawl through the opening in door E-85. Approach door E-87, but the controls require a passcode. Attach your explosive to the middle of the door, then add the detonator. Press the red button to start a 30 second countdown. Head into the side passage and behind the crates, then wait for the explosion. Go out and crawl through the hole in the door.
Go forward and right down another corridor with lightning, then head left and open the door. Quickly make your way through the poisonous gas, heading straight, left, right and left. Open the door and go through to get some fresh air for a while. Pick up the switch, then open the door again. Go straight and then left, through two open doors. Use the 2 switches on the left wall, then open the next door. Go through here to get some more fresh air.
Pick up a second switch from the floor in here. Continue through 2 more open doors, then read the messages and logbook. Insert both switches on the red crate here, then flip them both and use the Local Control panel to open the door. Enter the next room and press the Open button to trigger some form of scanner mechanism. Wait for it to finish, then press Open and head through the door. In the next room, press the Open button to trigger a decontamination process. Wait for this to finish as well, then press the Open button and leave the room.
Head left and over some crates to find another tripod that is missing its laser and 2 fuses. Search on the other side of the open E-92 door and take one fuse. Open the small door on the left and go through. Read the messages on the screen here, then pick up another fuse from on a nearby metal trolley. Open and go through the next door, then turn right to find an Energy Redirection panel. Adjust it to take this path:
Now you can open the door just to the right. Pick up the laser from on top of one of the crates in this room. Go back out and use the Energy Redirection panel again:
Return to the tripod. Put the laser on the tripod and the 2 fuses in the 2 slots on the generators. Turn on both generators, then use the panel to activate the laser. When it is finished, go and push on the round segment of the door until it falls through. Go straight ahead through door E-95. Turn left and take the cable from the open panel. Turn around and go to the open panel in the opposite corridor. Insert the cable, connecting the left and right sides. Open the door here, then open and head through 2 more doors straight ahead.
Turn left and go through the open door, then turn right and go along a corridor with lightning. Turn left and go out to a larger area, then turn right. Ignore door E-99 for now and turn right, going through a smaller open door. Open the door on the left, then go through to a second room and read the messages. Head through the next room out to another larger area. Turn left, then open the small door to the right. In here you will find a Data Recovery panel. Rearrange the pieces so they look like this:
Wait for the interface to be restored, then read the logbook, messages and notifications - this gives you the passcode of 34946. Return out of this room and look right to see door E-100 - this is locked. Turn around and go back down the large corridor, then turn right and back through 2 smaller rooms to return to a narrow corridor. Turn left and jump over some crates, then open the door at the end with passcode 34946. Search the cabinets in here to find a detonator and an explosive. Return to door E-100. Attach your explosive to the middle of the door, then add the detonator. Press the red button to start a 30 second countdown. Head around the nearest corner and wait for the explosion. Go out and crawl through the hole in the door.
Continue straight ahead through open door E-101, then turn right and jump over a crate. Open a small door on the right and go inside to read the messages and logbook. Continue into the next room and read the logbook on the panel here. Leave this room and turn left, then go to the end of the corridor. Look to the left to see a Circuit Bypass panel. Click on the symbols to complete the circuit from left to right (2 bottom, 3 top, 1 top, 1 bottom, 4 bottom). Open to the door to the right and go through.
Read the logbook and messages. Now you need to flip all 5 switches around the room - this only works in a specific order, so keep trying until you find the right one. Leave this room and go all the way to the end of the corridor, then open the door and proceed through. The panel on the wall here will say that radiation is at acceptable levels, so open the door on the left and go through towards the reactor.
Head around to the elevator and use it to go down. Walk around and press the call button for the other elevator, then also use it to go down. Walk around and open the next door, then turn left and open door E-104. Go through, jump over some crates, and walk towards the door on the left.
Open the door and go through, then go through another door to reach an intersection. Continue straight, then turn right and enter the room ahead. Read the logbook and notifications, then search the cabinets to find a red cable. Leave this room, then turn right to enter a small gym. Go through the other exit from this room, then use your cable in the slots on the right to activate the nearby door. Open this and go through.
Continue to the next room (don't worry about the scanner, it won't hurt you) and read the logbook, messages and notifications. Head out through the opposite door.
Avoiding the intermittent laser, head to the right and crawl through the hole in door E-106. Turn left, then crawl through an open duct you will find on the right. Turn left when you exit, and go down the corridor. Keep going past several large doors on the right that are not working. Find two switches on the right near the end, and activate them both. Now you can go back and open door T-22. Go and sit in the seat at the front of the shuttle. Use the panel to run the diagnostics when prompted. Solve the Energy Redirection puzzle with 5 concurrent paths, then press one of the buttons to drive the shuttle forwards.
Turn around and open 2 doors to reach a larger area. Go right, then left, and open door E-27 at the end of the hall. Go through, then turn right at the end. Half way along an orange corridor, open a door in the left. Inside this room, read the notifications, logbook and messages. Open the next door, then go straight ahead, following the orange corridor around to the left. Turn right when you can, then go right along a larger hallway, opening a door half way along on the left. Read the logbook and messages here, then leave via the other door. Turn left and continue through the next open door, then turn right and head all the way along a very long corridor.
Try to open the door ahead, but it requires a passcode. Head down the corridor to the left, then around to the left twice into a small office. Read the logbook, notifications and messages to learn the passcode 82342. Go back to the previous door and enter this to open it. Open the side door from the bridge on the right. Go to the end of this corridor and open the door around to the right. Proceed into a server room.
Read the logbook, notifications and messages here, then remove the 2 damaged memory modules from the red slots in the servers. Go out through the other door, then turn right and left. Enter the hibernation room. You can use the controls to disconnect the hibernation stations, but you will end up killing the occupants. Open the empty chamber. Now turn around and go through the door behind you.
Follow the corridor around to the left. Open the door on the left at the end. Inside, go over to the Energy Redirection panel and adjust it as follows:
Now you can open the door here and go through. Look on the wall to find another Energy Redirection panel, which requires this solution:
Open the next door. Take the 2 memory modules from the desk, then read the logbook. Go back to the first Energy Redirection panel and leave the first solution alone, but now also connect the other pathway:
Now you can go through and open the next door from where you got the memory modules. Return to the server room and insert your 2 new memory modules in the red slots. Go to the screen in this room and wait for the interface to come up. It will display a Data Recovery panel, which needs the following solution:
Make your way back to the bridge. Sit in the chair and choose to Run Hyperdrive. Now return to the hibernation room and climb into the hibernation pod you opened earlier.
