SHAW: Are you ready?

HOLLOWAY: Yea.

SHAW: Let's do it.

On foot, the explorers press on - Holloway and Shaw in the lead. Their flashlights cut into the gloom.

SHAW: Prometheus, we're going in.

JANEK: Copy that.

SHAW: After you.

HOLLOWAY: After you.

Dark and cavernous. Weak daylight slants in. The explorers press into the darkness on foot. They move through a dark cathedral space, empty and bare. David looks around in fascination, his eyes raking the walls.

HOLLOWAY: What's back here, some kind of corridor? . . . Mr. Fifield, let's get a grid of the structure. I want the whole interior.

FIFIELD: If there's anything here worth looking at, these PUPS will find them.

HOLLOWAY: PUPS?

FIFIELD: Yea, PUPS. My PUPS. Howl-oooooooooooo! . . . Prometheus, we are now mapping.

JANEK: Copy that.

JANEK: Well I'll be damned.

The interior is a labyrinth. Corridors big as railway tunnels intersecting and diverging. The explorers wind their way deeper.

HOLLOWAY: Fifield, got a read?

FIFIELD: Yea, uh, PUPS are saying this way.

Massive Chamber: Holloway leads the explorers deeper into the complex. David trails the others, eyes raking the blank walls as if he sees something there.

HOLLOWAY: Look at this.

SHAW: Oh Charlie.

FORD: Jesus, sunlight's heating the water. Check out the humidity.

HOLLOWAY: Yea, look at the C02 levels, outside it's completely toxic and in here there's nothing. It's breathable.

SHAW: What are you doing? Charlie, don't be an idiot.

HOLLOWAY: Hey, don't be a skeptic. Right, there's something generating an atmosphere. . . David?

DAVID: Dr. Holloway is correct.

FORD: Cleaner than Earth, actually.

HOLLOWAY: They were terraforming here.

SHAW: Please don't do this . . .

HOLLOWAY: Ellie, I'm not wearing this thing anymore. Wish me luck, baby. . . . . woooooooooo! hahaha!

SHAW: You crazy bastard.

FIFIELD: Prometheus, connect our C-Cameras if you want to continue watching this freak show. We're taking our helmets off.

RAVEL: Copy that, switching feeds.

CHANCE: Well come on, pay up.

RAVEL: Pay . . . pay what?

CHANCE: What do you mean pay what? Somebody's manufacturing breathable air down there. That, mate, is terraforming.

RAVEL: No-no-no, the bet was why we came here. If you had said that dead old man wanted to talk to Martians, then I'd pay.

CHANCE: Oh come on, a hundred credits. Put it towards a lap dance with Miss Vickers, how about that, hey?

FORD: It's minus twelve in here.

MILLBURN: Then why is this water not frozen?

FIFIELD: Maybe it's not water.

MILLBURN: Maybe it's Martian piss.

FIFIELD: Is that you're uh, scientific theory, is it . . . Mr. Biology?

David notices something on the wall and investigates.

On the wall is a plaque with alien symbols and they appear to be electronic.

He touches the plaque, a thick liquid is now on his glove fingers.

DAVID: Impressive.

He presses a series of alien switches. A strange rumbling noise sounds down the corridor, followed by a wall of light quickly tracing the walls. The rest of the group hears the strange sound and stop in their tracks. Holloway sweeps his light that way.

MILLBURN: Uh, what was that?

David, who is several yards away from the group, looks down the corridor as they call for him.

SHAW: David? . . . David?

HOLLOWAY: David?

Apparitions appear before him. A pale, luminous giant fifteen feet tall, with hollow eyes and a grotesque snout. they stride towards him. David stands stock-still by the wall, with a sizzle of static, he experiences the creatures passing through him. Having passed David, the Apparitions now race towards the rest of the group. The sound comes again: an unearthly sound. Pandemonium. Everyone scatters. Holloway knocks Shaw out of the way.

HOLLOWAY: Ellie!

Shaw watches as the Apparitions race by. Holloway stares at the Apparitions in fascination.

HOLLOWAY: What the hell was that?

FIFIELD: Oh I'm really glad we didn't bring any weapons. . . Who's idea was that?

FORD: What was that?

HOLLOWAY: Come on, let's go. Keep up.

SHAW: Where did they go?

Holloway and Shaw round a corner and stop in their tracks. Holloway and Shaw lead their party up to a massive door, sealed tight. In design and scale, undeniably important.

HOLLOWAY: There it is . . . there it is.

The scientists stand frozen. In front of them lies a dead giant. An Engineer. If he were standing, he would be fifteen feet tall. The explorers move closer.

SHAW: Oh my God, Charlie. We found them.

He is roughly human in shape. Barrel-chested. Withered to the bones. There are bulky protrusions fused with his flesh: hard to say whether they are equipment or parts of his body.

FIFIELD: What d'you mean them!?!

The giant lies frozen in a convulsion of agony. His corpse is marred by hideous wounds: slashes that cut through bone.

HOLLOWAY: Looks like a door and he's been decapitated by it.

Janek watches the stereoscopic feeds from the explorers' flashlights, the ship's powerful imaging systems stream data.

VICKERS: Son of a bitch . . . they were right.

JANEK: Heh-heh-heh, did you want them to be wrong?

HOLLOWAY: David, please tell me you can read that.

DAVID: Perhaps.

FIFIELD: Uh, I'm out with it.

SHAW: Hey Fifield, where are you going?

FIFIELD: What! . . . Look, I'm just a geologist, I like rocks, I love rocks. Now it's clear you two don't give a shit about rocks, but what you do seem to care about is gigantic dead bodies. And I really don't have anything to contribute in the GIGANTIC DEAD BODY ARENA! . . . I'm going back to the ship . . . if you don't mind. . . Anyone want to join me, hey? You stayin'?

MILLBURN: Uhh . . . no, ship's good.

FORD: Yea, ship very good. . . . Congratulations on meeting your maker.

SHAW: Thank you.

HOLLOWAY: Pull yourself together, man.

MILLBURN: And I thought you were the crazy one.

Shaw joins Holloway beside the dead Engineer. Touches the corpse in her own turn. It�s hard as stone: ossified. She traces the ancient, terrible wounds.

SHAW: Do you have the carbon reader? . . . . Thank you.

HOLLOWAY: How long's it been dead

SHAW: 2,000 years, give or take.
