Lexine: "Sam? Honey, can you hear me? This signal's terrible. Try moving around. That's better."
Caldwell: "Sorry Lexine, I was next to the recharging station. Are you calling about tonight?"
Lexine: "No, because then it wouldn't be a surprise. I'm mad at you, Sam Caldwell."
Caldwell: "Why?"
Lexine: "Because you somehow forgot to tell me what you're doing today.
Caldwell: "It's just a routine excavation."
Lexine: "Routine!?! You're extracting a Marker! My supervisor Leon's nuts with excitement! Do you know he's a Unitologist? This is a big deal!"
Caldwell: "Leon's always been nuts. Anyway, we don't know if it is a Marker, or just a big rock. That's why we're doing this, so the boffins can study it."
Lexine: "Sam Caldwell, if you had an imagination, you'd be dangerous."
Caldwell: "We'll see about that tonight."
Lexine: "Oooh, I look forward to it. I gotta go honey. I love you."
Caldwell: "I love you too. Later."
Logging off from the call, Sam gets back to work.
Sterling: "Sam, come on. Get suited up quick or the only date you'll have is with an overtime sheet."
Caldwell: "Say no more. Lexine's already mad at me; she'd kill me if I bailed on her."
Sterling: "Well, all we're doing is waiting for you, so don't expect me to make excuses if we're still working tonight."

You start with only the Rivet Gun.

"Sam, is your helmet secure?"
Cooper: "Sterling, this is Cooper. We're already at the extraction site. Where the hell are you guys?"
Sterling: "We're on our way, boss. We'll be there in a minute."
Egan: "You see the vidlog of the Marker that's going around? Looks just like the one back on Earth."
Sterling: "You mean, what the Unitologists claim is back on Earth. Also there's one big difference. Earth is Earth, while this beautiful place we call Aegis VII is nothing but a ball of space rock. I mean, come on, what are the odds?"

As you stroll through the area, there are boxes containing goodies.

Sterling: "And there it is..."
Caldwell: "It's bigger than I imagined."
Cooper: "About time! Give Banks a hand fixing up the track and loader."
Sterling: "All 3 of us?"
Cooper: "Damn straight. If this thing gets so much as scratched, Chief Barrow will have us all scrubbing airvents."
Caldwell: "Hey Banks, what do you need?"
Banks: "The wind's blown out some of the track we laid. Get it back into place, and rivet it tight!"
Caldwell: "That thing's gotta be man-made..."
Sterling: "Hurry up! Cooper's already pissed that we're late!"
Sam: "Copy that Sterling, I'm right behind you."

Okay, time to go to work. Shoot rivets at the 4 bolts to fix the track.

Banks: "Good job. Now get the loader's arms in position. One of you TK it, the other 2 rivet the joints."
Caldwell: "Egan, I'll take these 2. And watch your aim, I don't want to end up on crutches like Matthews."

Now, you need to shoot a pin on the right side of the cart. However, you need to use the secondary fire mode to do the job. Do the same with the pin on the other side.

Banks: "Alright... Egan and Sterling, you get the loader into position by the Marker. Caldwell, you finish the job."
Sam looks back over the Marker.
Caldwell: "Lexine's right. Leon would flip if he saw this."

Now, use Kinesis to grab the cart and move it to the left.

Cooper: "Looking good. Counterbalance is stable... Gyros operational... Ready for load... Standby, I'm starting a 5 down."

Operate the terminal.

Cooper: "5, 4, 3, 2, 1, mark!"
Suddenly, there's a bright white flash which disorients everyone.
Sterling: "What the hell just happened?"
Egan: "Ah... My ears are ringing!"
Cooper: "Shit! Whatever it was blew out Gravity Tether 16! Caldwell, Egan, Sterling, get over there and stabilize it before we have a mini black hole on our hands! Me, Banks, and Bear will get the marker inside!"
Egan: "16... Which one's that?"
Cooper: "The closest one, you idiot! Head down Megavent 24, you can't miss it!"
Sterling: "What the hell was that?"
Caldwell: "Come on guys, we've gotta get a move on!"
Sterling: "Sterling to central... I'm outside. Can you tell me what that bang was? Shit! The flash must have knocked out comms too."

You stop in front of a door. Open it, because in case you didn't know, you get to do that yourself in this game. In the next room, you get to interact with a terminal.

"Can't see anything without the lights."
"There should a box of Glow Worms in the airlock storage chamber. We can use them."

Open the door. In this room, you have your first Free Look area. Unlike the others, you have an unlimited amount of time to look. In front of you is a box, and there's a locker on the right side of the room. Anyway, look to the left to find your Glow Worm, and take one.

Caldwell: "You were right. I found a Glow Worm. Look around. We should find some supplies before we head down."

Now you can see better. Activate it to proceed. Some goodies are in the alcove on the left. There's a Text Log on the ground to the next room. In the next room, use the terminal.

Caldwell: "Airlocks are engaged. We should be fine now."
Yells can be heard nearby.
Sterling: "Shit! Sounds like someone's in trouble! Hold on!"
Egan: "Wait a second! We don't even know what going on in there!"

Be brave and open the door. Inside, a miner hacks away at another on the ground. There's a box and a locker here to scavenge.

Sterling: "What the fuck? Zochenko, what in god's name are you doing? Get off him!"
The crazy guy obeys, but menacingly approaches...
Sterling: "Zochenko, stop! I'll... I'll shoot you! You know these rivet guns pack a punch!"
He shoots the man, making him drop his weapon, but not otherwise phasing him. The crazed miner lunges forward, knocking everyone down.
Sterling: "Shit! Help me! He's out of his mind!"
Caldwell: "Sterling!"

Blast the crazy guy (AKA an Insane.)

Egan: "Oh man... I can't... I can't believe it..."
Sterling: "Sam, grab that rock saw, we may need it."

Take the axe. Now you can perform melee attacks.

Egan: "Jesus Christ, we just killed someone!"
Sterling: "We don't have time to think about that! If we don't fix that tether fast, we'll all be dead! Move! Look out! More of them! They've all gone fucking crazy!"

Additional Insanes run in. On the other side of the room are more boxes and another locker.

Caldwell: "Okay guys, let's go. Tether 16 is a few levels down."

Heading down the walkway, you pass 2 lockers on the wall. Open them to find a goody and a Text Log (2nd locker.)

Caldwell: "Up ahead... You guys see that?"
Sterling: "It's blocked. Looks like they had problems down here before.
Caldwell: "This is a bad idea. We shouldn't have come this way!"
Sterling: "Sam, calm down. Cut that security line. Use the rock saw you picked up."

Use the melee slash to destroy the barricade.

Egan: "Coming through!"
Suddenly, a voice that sounds like Lexine's is heard, though only Sam hears it.
???: "Turn back Sam! Don't go any further!"
Caldwell: "Lexine?"
Sterling: "They must have put this here to stop people coming up."
Egan: "I can't believe we're doing this..."

Bust another barricade. At the bottom, a crazed miner sits on her knees clutching a knife.

Caldwell: "Stop! Don't do this!"
Laughing, she stabs herself to death.
Sterling: "What the fuck?"

Open the door.

Cooper: "We're almost home with the Marker already, but I don't see the tether operational yet." (Alternatively, sometimes he says this: "This is Cooper. Just checking in. How are you doing?")
Egan: "We're on it boss, just... Just give us some time." (Or, in response to above: "We're making our way through the Megavents, boss. Some strange shit's going down here.")
Cooper: "I don't want excuses, Sterling; I want that gravity tether fixed.
Egan: "It's coming man... It's calling us..."
Sterling: "Shhh... You hear that?"
???: "They're coming... There's nowhere to hide... God help us all... Is anyone left?"
Sterling: "Someone's trapped in there! I'll check it out, and meet you in the gravity tether room. Go!"
Egan: "It's death, Sam... Can't you see it?"
Caldwell: "Egan, what the hell are you talking about? Get a grip!"
Egan: "But, Zochenko... We killed him!"
Caldwell: "I know, but you saw what happened in there! It's like... It's like it wasn't really him! We should take that plasma cutter too. Listen to us... This is all wrong..."

Take the Plasma Cutter. For some reason, you can use the Glow Worm here, though it is hardly necessary.

Caldwell: "Come on, Egan, I don't want to waste anymore time."
Climbing up a ladder, Egan slips and drops his rivet gun into the abyss.
Egan: "Shit! No, dammit, my rivet gun!"

An Insane rushes you from behind and grabs you.

Caldwell: "No! Get off me! Christ, what the fuck's going on!?! Egan, you okay?"
Egan: "Needs us... Needs us... To make it whole..."
Caldwell: "Quit babbling! Let's just do this and get the hell out of here!"
Egan: "Look out, there's more!"
Caldwell: "Egan, get behind me!"

More Insanes come running.

Egan: "You don't understand! It's not right! We have to end it!"
Caldwell: "Shit! Egan, stop! What are you doing!?!"
Egan: "You can't stop it! You can't fight it!"
Caldwell: "Don't make me shoot you! Egan, please!"

Kill the Insane Egan.

Caldwell: "Oh my god, Egan, I'm sorry..."
???: "I was just trying to help... It needs our help, Sam..."
Cooper: "Caldwell, this is Cooper... I can't reach Egan or Sterling, how are you guys doing?"
Caldwell: "Something bad's happened... Egan went crazy, and everyone down here's trying to kill us! Egan's gone..."
Cooper: "You're breaking up... I can barely hear you. Just get on that tether before it starts a feedback loop and takes everything down with it!"
???: "Don't trust them... Don't trust anyone..."

Open the door. Inside, a miner bangs his head on a wall. There's a Rivet Gun Upgrade here.

Caldwell: "What's going on?"

An Insane charges.

Caldwell: "Are you okay?"
Hearing his voice, the Insane charges...
Caldwell: "Come on, don't make me do this! I'm trying to save you!"

You have some time in Free Look. There are some supplies: on the upper walkway in front; on a panel to the left, and on the shelf on the right. The terminal you need is here, but there are broken electrical cables whipping around near it.

Radio: "Central to Caldwell Stasis modules are standard for all mining personnel. I know you haven't been trained in it, but if you find one, it could come in handy."
Caldwell: "There, perfect."

Whaddya know, there's one just lying around by a corpse. Pick up the Stasis Module and you can now use Stasis. You head back to the wires.

Caldwell: "OK, just need to Stasis it at the right moment..."

When the wires whip upward, blast them with Stasis. You'll move to the terminal. Here is your first terminal 'puzzle' part. This one has no obstacles to deal with. Easy! When done, you head over to control terminal. Activate it.

Cooper: "Caldwell, I hope you can hear this, because comms are shit out here. Good job with the tether. We're enroute with the Marker to storage. Meet us there, over."
Caldwell: "Copy that... Caldwell, out."

Go through the door back onto the walkway.

???: "They all have to die... You know that, right?"
Caldwell: "Get out of my head!"

Ahead, more Insanes are on the catwalk. The one standing by the crate can't be harmed until he comes after you. Heading back the way you came, Lexine calls in...

Lexine: "Sam, are you okay?"
Caldwell: "Lexine! God, it's great to hear you. Listen, things are pretty bad down here."
Lexine: "No, I mean, did you hear? Some Unitologists just killed themselves in Union Square! There's pictures... It's awful... Leon was there..."
Caldwell: "Things are getting crazy all over the colony... We were attacked and Egan flipped out... I killed him, Lex!"
Lexine: "I... Sam, say that again."
Caldwell: "I killed Egan... I had no choice, he tried to kill me!"
Lexine: "I'm scared. Someone just told me some sectors are losing oxygen too."
Caldwell: "Hold on, that could be from the blast. The life support room isn't too far from here."
Lexine: "You think that's what's wrong with the oxygen?"
Caldwell: "Just hold tight baby, I'll fix it, I promise."
You hang up just as an Insane shows up.
Caldwell: "No! Stay away from me!"

Kill it, and as you head on...

???: "You're going the wrong way... "
Uh, thanks voice. Correcting path...
???" :Death is the answer, Sam... It's so obvious..."
Caldwell: "Life support is through here."

Right by the door is a Plasma Cutter Upgrade. Open the door and enter the zero gravity area.

Computer: "Warning. Colony life support off-line."
Caldwell: "This is it... Hope the antigravity still works."

You have some time to Free Look. There's some boxes floating around. You can probably get any you miss since they float through the air and you don't have to move yet. To proceed, you have to jump to the indicated platform. You have to solve another puzzle on this terminal. This time, the last node has firewalls outside the line.

Computer: "Colony life support system now online."

You must make another jump to the exit platform. But first, you can find an Audio Log floating around (can also be found during Free Look earlier.)

???: "Don't tell Lexine! Don't tell her anything!"

Open the door. Lexine calls you up.

Lexine: "Air's circulating again! When are you getting back?"
Caldwell: "I'm on my way back... I... I can't seem to focus..."
Sterling: "Why'd you kill me? I'm not a monster."
Lexine: "Sam? Sam, what's the matter?"
Caldwell: "Nothing. Just stay out of sight, OK?"
Lexine: "Be careful, I love you."
???: "I love you... It loves you..."
Caldwell: "What the hell?"
???: "Did you hear that? Why aren't you listening?"

You are in an area deemed to be dark enough to use the Glowworm, but you don't need it.

???: "Why did you let me go alone, Sam? Why?"

Another Insane attacks. There's some goodies here. When the Insane falls, it turns out to be Sterling.

Sterling: "Death is the answer, Sam... You'll see... We can't stop it..."
Caldwell: "Sterling? Oh god, I thought you were... I've got to get out of here. Back to Lexine... We've got to stop it! Is this even real?"

More Insanes attack. Some boxes are around here.

Caldwell: "No! It's not real!"
???: "We're all going to die down here..."
Caldwell: "We're not going to die!"
???: "Look out! They're all around you! You've got a job to do, and you know what it is!"

A final wave of Insanes come at ya.

A lift full of more men arrive.
Caldwell: "No! Stay out of my way! I need to get to Lexine, you hear me!?! She needs my help!"
One of the men shoots Sam. Mortally wounded, he is unable to continue fighting.
Caldwell: "No... Lexine... Help me... What? You... You're not..."
Officer: "Hostile is down. Repeat, hostile is down. Good shot, sir."
McNeill: "Shooting one of your own is never good. He's not even packing a gun." (Um, you were packing 2 VERY lethal weapons.)
Officer: "You're shitting me? This is the guy who slaughtered his entire crew?"
McNeill: "Why'd you do it, son? All these people never did anything to hurt you."
Caldwell: "Lexine..."
McNeill: "He's gone. Call Commander James and get Dr. Sciarello down here. He's going to have a busy day."
???: "Sam, I love you..."
