The game's audio diaries can only be found in the Marine campaign. They primarily consist of recordings from Weyland and Groves detailing their discovery of the Xenomorphs on BG-386 and their subsequent experiments with them, as well as other recordings made by the hapless colonists and Marines that are caught up in the subsequent Xenomorph outbreak that overruns the planet.
Logs are arranged here by level per the game's audio diary menu — which is neither chronological nor necessarily the order in which the player will collect them.
Rodriguez, P. T. — Entry 3
"Bugs everywhere. They're coming through from some place top of the pump room. Must be a way in from outside there... Shit!"
Simons, D. — Entry 1
"I did what I had to... Those things would've got me too if I hadn't! I could hear my friends banging on the door... Screaming as those things start to... I did what I had to. I didn't want to die!"
Hope, C. — Entry 3
"...know how many of us are left. Those things are everywhere. They seem to want to take us alive. I don't know why. We don't have any weapons, we don't know what's happening. Someone will come, though. They have to."
Brewer, N. B. — Entry 1
"They can't fool me. People are going missing. And they're being turned into androids. There's people walking around who aren't even human at all. My wife tells me I'm crazy — and that's how I know she's one of them too."
Brewer, N. B. — Entry 2
"These... demons have come to cleanse us. My wife and children were filthy, that's why the demons took them. I... I have been spared. New life grows within me. Soon, I will be reborn."
Hope, C. — Entry 1
"Near as I can tell, those creatures are coming from the refinery. And they're not just killing people — they're taking them back there, too. No word from the people at the lab. Those bastards better have sent for the Marines! Otherwise we're all dead."
Weyland, K. B. — Entry 1
"Everything we do here hangs by a thread, but the potential returns are vast. If Weyland-Yutani can leverage the hunters' technology, we can monopolize human commerce. Every colony, every spacecraft, every weapon manufactured by me, purchased from me."
Weyland, K. B. — Entry 2
"This species has demonstrated that humanity's ruthlessness is nothing. Mankind legislates and debates, allowing rage or compassion to clip our wings. The Xenomorphs have no such weaknesses."
Rodriguez, P. T. — Entry 2
"Guard duty again. How come I always get the crappy details? Fucking Tequila. Treats me like shit but nursemaids the new Rookie. Waste of fucking time... No way that kid will make it through this."
Hope, C. — Entry 2
"Janie, my wife, she got one of those things on her face. I couldn't pull it off, so I got a knife... It just burnt right through her, until there was nothing left."
Rodriguez, P. T. — Entry 1
"First sitrep: This place is a shithole. Further sitrep: It's a total shithole, we're in shit shape, no one's got a fucking clue what to do and I heard none of the officers made it. That last part ain't so bad, I guess."
Jones, T. J. — Entry 1
"Beats me why we go into these places just to save private operations like this. This is Weyland-Yutani's mess, they should clean it up. We're Colonial Marines, not a corporate security force."
Aquila, T. — Entry 1
"Real shame the Rookie got left behind. Sure, he's wet behind the ears, but he's got heart. Maybe that'll be enough to see him through. Tequila, out."
Ames, J. — Entry 2
"It's quiet now. I haven't heard any screams for a while. I can hear them moving around some times, coming up from below. There's something else down there too. Something big."
McManus, J. — Entry 1
"Katya... The way she talks, even the way she smiles... I wondered why they laughed when I started talking to her in the canteen that morning. They make those things so lifelike these days."
Groves, H. G. — Entry 3
"I could see Mr. Weyland's excitement as he met me on the shuttle platform. The research facility is impressive, but it was the look in his eyes... Something has his full attention. I've never seen him so alive."
Weyland, K. B. — Entry 3
"Even now I can't help but admire her, despite all she did to hold us back. Three times she faced them; three times she obstructed our progress. She showed a strength that few possess. If she had only realized the magnificence of what she sought to destroy."
Groves, H. G. — Entry 4
"Karl showed me the ruins today. They predate the human epoch. Neutrino and Boson flares indicate technology still functioning, after countless thousands of years."
Biggs, G. — Entry 2
"I should home by the end of next month, this time for good. You were right, and I was wrong, honey. There are better employers than Weyland-Yutani."
Biggs, G. — Entry 1
"Webster wasn't on duty today. Reassigned to the refinery, they said. But I don't believe them. Not after the other disappearances. There's something they're not telling us."
Ames, J. — Entry 1
"Shit! Honey, you wouldn't believe what we've found! I can't say much, they read our messages home, but — we're all getting the biggest fucking bonus you ever saw! Soon as I get home, we're getting a bigger place."
Groves, H. G. — Entry 6
"All our theories seem to have been corroborated. The hunter architecture clearly binds their culture into a ritualistic relationship with the Xenomorphs."
Standen, C. — Entry 1
"Didn't know half the guys I came down with. Didn't matter much. Bugs got them all anyway. If you find this, do a brother Marine a favor and get a message to my girl. Tell her... Tell her I tried my best to get back home to her."
Standen, C. — Entry 2
"I... I can feel it moving! There's stuff they can do to save you, even if you've got one inside of you. They told us that in training. I just have to stay alive long enough for them to find me."
Hoole, J. M. — Entry 1
"I hated this place when it was operational and I hate it twice as much now. Who builds a colony base on seismically unstable ground? I logged the tremor damage and burned back the jungle grown. If the planet wants this place back so bad, it can have it."
Haggis, M. Z. — Entry 1
"No one knows what the hell's going on, or where these things came from. Trying to restore power here to increase our chances. Five will get you ten those assholes dug up something they shouldn't have."
Dunn, I. — Entry 1
"Obsession is the driving force to progress. Weyland proves that. We could never have done any of this if the colonial authorities had got here first. He's a great man. We forgive great men terrible things, as long as they achieve their aims."
Groves, H. G. — Entry 7
"Mr. Weyland is convinced we shall find Xenomorph remains somewhere within the pyramid's heart. What drives this conviction, I'm not sure, but I get the feeling that Karl knows more than I'm aware."
Jones, T. J. — Entry 2
"Jungle infested with Xenomorphs. We've been unable to located their nest. Reports of some new kind of Xeno we haven't seen before. Faster, stronger, even more dangerous. We're in a bad way. Where's Van Zandt to reinforce us?"
Groves, H. G. — Entry 8
"My eyes have been opened! The hunters did not merely worship the Xenomorphs, they bred them. For the hunters, facing the Xenomorph must have been the ultimate right of passage. One has to contemplate whether the hunters discovered these creatures... or created them."
Weyland, K. B. — Entry 4
"The Xenomorphs' essence is a repudiation to a universal truth — survival through merciless necessity. They are uncompromized by remorse or pity. I admire them. I strive to emulate them."
Weyland, K. B. — Entry 5
"I remember all those centuries ago a tiny jumping spider, smaller than a lentil. It turned and watched me. I wonder, what's going through your tiny mind? With some dread, I suspect the Xenomorphs ask themselves the same question about us."
Groves, H. G. — Entry 9
"Today we entered what appears to be a sacrificial vault for impregnation and gestation of Xenomorphs. Despite the fact that the ruins predate modern hominids, I cannot shake the notion that these plinths are perfectly proportioned for human victims."
Groves, H. G. — Entry 10
"We have discovered something that utterly redefines my understanding of the Xenomorphs. I knew they were robust, able to withstand environmental extremes beyond any other complex lifeform, but to discover her here! So ancient, so worn by time, yet alive! Aware."
Groves, H. G. — Entry 11
"Returning to the Matriarch's chamber today brought such a sense of humbling awe. Imagine, an intelligence captive yet aware for tens of thousands of years... How can mortal man conceive of such eon-spanning resilience?"
Weyland, K. B. — Entry 6
"I have been born of such delicate material. I need to evolve, to become as irrepressible as you. Image what I might become. Your biology wedded to hunter technology. A new paradigm in the universe."
Tyrell, L. — Entry 1
"Bryce has disappeared. He was talking about striking over conditions at the refinery and new he's suddenly resigned? Bullshit! I hear rumors about secret labs and human test subjects. What the fuck is Weyland up to?"
Jupiter, L. L. — Entry 1
"Stuff goes on here, you know? You hear one of the refinery stiffs is missing, and next day, they got a new host body for Doc Groves and his pets to play with. I don't as questions. All I'm saying is, stuff goes on here."
Hoole, J. M. — Entry 2
"The geologists say those caves below the refinery run deep. Got drunk one night with one of them. He said some of the tunnels there weren't natural. And he didn't mean man-made either."
Hoole, J. M. — Entry 3
"Well, they sure found something down there. Suddenly we got company suits all over the place. Somebody said Weyland was here. I didn't see him. Saw the combat androids, though. Man, those things creep me out."
Fuchs, T. — Entry 1
"Evidence here bears out my theories about the relationship between the hunters and the Xenomorphs. They are sacred prey. The means by which initiate hunters prove their bravery and skill. To the hunters, the Xenomorphs truly are the galaxy's most dangerous game."
Banner, D. — Entry 1
"We keep on uncovering Xenomorph images among these ruins. The creatures obviously had some important meaning to the hunters, but as what? Pets? Enemies? Gods? I'm convinced the answer is here somewhere."
Banner, D. — Entry 3
"My requests for more excavation personnel have met with... limited success. Weyland's operations get priority. Damn Weyland... If it isn't about his precious pyramid or Groves' pet monsters, he just isn't interested."
Groves, H. G. — Entry 12
"Within hours of encountering this hag Queen she is producing Eggs. The presence of potential hosts has stimulated her. As I observe the first Egg exude from her huge, quivering ovithorax, I felt an instinctive chill of fear."
Weyland, K. B. — Entry 7
"I am beginning to understand. The Xenomorphs. Their hive mind. So vast. So ancient. Can it be that their consciousness, on some level, spans their entire domain?"
Banner, D. — Entry 4
"Something's happened at the lab. The monorail station's been overrun by Xenomorphs. The Matriarch creature was with them! If she's allowed to establish a Hive... This is a disaster! Weyland's completely lost control."
Banner, D. — Entry 5
"My team.. They're all gone... Those things took them. I've gotta get out of here and warn... No!"
Banner, D. — Entry 2
"I've been studying Xenomorph ruins for months. They're all over these ruins. We thought they were extinct on this world. If they're back though, then maybe the hunters are too."
Groves, H. G. — Entry 13
"And now to work. My initial sense of awe has given way to the thrill of what has fallen into our hands. A resource so pure that its worth to our research is immeasurable."
Fuchs, T. — Entry 3
"Groves hasn't given us much time before the science team start trying to access the data stored here. We were right! It's a tomb, built by the hunters to honor a great king or warrior lord of their race. The things we can learn about them just from this room..."
Fuchs, T. — Entry 2
"The whole corridor is rigged with some kind of hologram system. Despite its age, I believe it's still operational. How it's triggered or what it projects remains unknown. We're still trespassers here, with no idea how this place really works."
Weyland, K. B. — Entry 8
"Through you we're beginning to understand the complexity of your hive structure. Your hierarchy is as adaptive as your biology. A true meritocracy, where the lowest vassal can rise to rule."
Groves, H. G. — Entry 14
"Such provenance. For years we've been working with broken scraps gathered from here and there. But now we can tap the very source of this magnificent species."
Groves, H. G. — Entry 15
"Nature creates beauty in many forms. And you, Six, you are the most beautiful of all. I shall break you, Six. Bend you to our purpose. Humanity is the new power in the universe."
Weyland, K. B. — Entry 9
"I have to posses the secrets of the burial chamber. If it holds what I suspect it must, it will secure Weyland-Yutani as the dominant force for progress and profit. The wrist computer is the key, to many things."
Weyland, K. B. — Entry 10
"Despite the chaos, you must know I was prepared for your escape. Your species' irrepressibility is its finest attribute. It is an attribute I will eventually break. That is my goal. To harness your species. To dominate."
Weyland, K. B. — Entry 11
"Despite watching you grow these weeks, observing intimately for hour after hour, you still fill me with awe. You are a bio-technical treasure waiting to be exploited. Each gene sequence, each enzyme, each protein is a key to great wealth and power. You are special, Six, so very special."
Weyland, K. B. — Entry 12
"We know there are propaganda chemicals transmitted between your brothers and sisters. We known you have rudimentary broad-spectrum sight. That you can hear. But there is more to your kind, isn't there? A hive mind, beyond any clumsy biochemical exchange. What is buried in your mind, I wonder? What precious commodities?"
Weyland, K. B. — Entry 13
"And now, my creation, my... daughter, you will face the true test of your species. I wonder, are you ready? Is there even a question that you will hesitate?"
Katya — Entry 1
"Weyland's behavior is increasingly erratic. Is his obsession part of the personality coding, or is it a replicating error between different generational models? I know he doesn't like me. Perhaps I remind him too much of himself."
Weyland, K. B. — Entry 15
"I possess knowledge and experience spanning centuries, but I lack the single causal beat that defines me. In that instant, Charles Bishop Weyland saw them both for the first time. Two creatures, each of them perfect in their own way, each of them unimaginably valuable. At the moment, my ancestor, my predecessor, my... template — he saw my future."
Weyland, K. B. — Entry 14
"A dying billionaire embarks on a voyage of discovery to a frozen wasteland. Experimental technology stores his memories. He knows his chances are slim, but it is not the cancer in his lungs that will bring him to his end. Charles Bishop Weyland's final moments are lost to me. Unlike everything else, they cannot be recovered, but they continue to define my existence."
Groves, H. G. — Entry 16
"It is ridiculous, I know, but these combat androids... They unnerve me unlike any Xenomorph. On one hand, so human, yet on the other, utterly dead in every respect."
Groves, H. G. — Entry 17
"As our work here advances and the risks increase, Weyland expands the combat androids' remit. They arrived as mere hardware, but now they appear to outrank most of my staff. How long before they start giving orders to me, too?"
- Once the player has found all of the audio logs in Aliens vs. Predator, they will unlock the trophy/achievement "Harsh Language", named after a quote from Private Frost in Aliens.
- Several of Karl Bishop Weyland's audio logs reference the films of the Alien franchise, mentioning both Ellen Ripley (albeit not by name) and Charles Bishop Weyland.
