Newt: We'd better get back, 'cause it'll be dark soon, and they mostly come at night... mostly.
Smart Gunner Private J. Vasquez: Hey, mira. Who's Snow White? Drop Ship Pilot Corporal C. Ferro: She's supposed to be some kind of consultant. Apparently she saw an alien once. Communications Technician Private W. Hudson: Well whoopee-fuckin'-do, hey, I'm impressed.
Bishop: I'm afraid I have some bad news. Private Hudson: Well that's a switch.
Carter J. Burke: I thought you were smarter than that, Ripley. Ellen Ripley: Well, I'm happy to disappoint you.
Corporal Dwayne Hicks: Guess the new lieutenant's too good to eat with the rest of us grunts. Private R. Frost: Man's definitely got a corncob up his ass.
Communications Technician Private W. Hudson: Hey top, what's the op? Ground Troup Commander Sergeant A. Apone: You'll love it, it's a rescue mission. There's some juicy colonists' daughters we have to rescue from their virginity.
[Pulling out his pump-action shotgun.] Hicks: I like to keep this handy for close encounters.
Hudson: They're coming outta the walls. They're coming outta the goddamn walls!
[All doors have been welded closed against the advancing aliens.] Hicks: Now all we need is a deck of cards.
Lt. Gorman: I'm coming in. Private Hudson: I feel safer already.
Van Leuwin: Thank you, Officer Ripley, that will be all. Ripley: God damn it, that's not all!! 'Cause if one of those things get down here then that will be all! And all this bullshit that you think is so important, you can kiss all that goodbye!
[To Queen Alien who's about to grab Newt.] Ripley: Get away from her you bitch!
Ripley: Well, someone's gonna have to go down there, take a portable transmitter and patch in. Hudson: Yeah, sure, with those things running around? You can count me out. Hicks: Well I guess we can count you out of everything then. Hudson: That's right, man. Bishop: I'll go. I mean, I'm the only one qualified to remote-pilot the ship anyway. Hudson: That's right, man, Bishop should go. Good idea!
Ripley: These people are here to protect you. They are soldiers. Newt: It won't make any difference.
[On whether she would return to LV-426] Ripley: Now please leave. I am not going back, and I am... I would not be any good to you if I did.
Ripley: What do those pulse rifles fire? Gorman: 10 millimeter explosive tip caseless. Standard light armor piercing round. Why?
Cpl. Hicks: Hey! I know we're all in strung out shape but stay frosty and alert. We can't afford to let one of those bastards in here.
Ellen Ripley: I don't know which species is worse. You don't see them fucking each other over for a goddamn percentage!
Sergeant Apone: All right, people, what are you waiting for? Breakfast in bed? Another glorious day in the corps! A day in the Marine Corps is like a day on the farm. Every meal's a banquet! Every paycheck a fortune! Every formation a parade! I LOVE the corps!
Ripley: They cut the power. Private Hudson: What do you mean "they cut the power"? How could they cut the power, man? They're animals!
Private Hudson: Hey Vasquez, have you ever been mistaken for a man? Private Vasquez: No, have you?
Private Vasquez: Look man! I only need to know one thing: where they are.
Hudson: Is this going to be a standup fight, sir, or another bughunt? Gorman: All we know is that there is still is no contact with the colony, and that a xenomorph may be involved. Frost: Excuse me sir, a what? Gorman: A xenomorph. Hicks: It's a bughunt.
[When they are dropped over LV-426] Private Hudson: We're on an express elevator to hell - going down!
Bishop: I may be synthetic, but I'm not stupid.
[Lieutenant Gorman orders the troops to unload all their weapons before the first alien encounter] Private Frost: What the hell are we supposed to use, man? Harsh language?
Private Hudson: Yeah, but it's a dry heat!
Corporal Hicks: Remember: short, controlled bursts.
