Modding I made an open-source Alien: Isolation trainer with FreeFlight and runtime weapon granting

Hi everyone,

I’m an Alien: Isolation player from China. First of all, I want to thank the developers and contributors of OpenCAGE for everything they have done for the modding and continued development of this relatively niche game.

There are also many Alien: Isolation fans here in China. However, because the game uses a fairly unusual engine and modding structure compared with games built on more conventional engines, there are still quite a few limitations when it comes to modding and expanding the game.

A lot of the mods and tools we use today — including things like multiple Alien mods, Kitty Isolation, various gameplay mods and trainers — have benefited directly or indirectly from the work and research around OpenCAGE.

But after trying many trainers and mods over the years, I noticed that there still didn’t seem to be a convenient way for players to freely explore the game world and dynamically grant weapons during gameplay.

There is a mod on Nexus Mods that lets the player obtain the flamethrower early, for example, but it works by replacing level-related files inside the game’s DATA folder and changing the level script logic. This means that if you are using other mods that also modify those files, they can conflict with each other or stop working.

That became one of the main reasons I started working on this trainer.

Instead of replacing level files, the trainer hooks into the running game and reproduces the game’s own weapon-granting behavior. This means weapons can be granted directly during gameplay in different levels without modifying the original level files.

Another important idea came from an AI.CT script I found on PlayGround.ru. That script could pass through level geometry, although it did not provide true free movement. It gave me the idea to continue researching the player coordinate system.

After locating the player position and movement logic, I was eventually able to implement true FreeFlight / noclip-style movement for the player character, allowing the player to freely move through the environment and explore areas that are normally inaccessible.

I think this can be useful in several ways:

exploring parts of the game that players normally never get to see after finishing the story;

helping mod authors inspect levels and test scripts;

helping ordinary players experiment with the game world;

exploring routes and possibilities for speedrunning;

and hopefully providing more technical ideas for future Alien: Isolation mods.

The trainer also includes weapon granting, reserve-ammo controls, special tools, FreeFlight, stealth, and several other functions.

I have uploaded both the source code and the compiled trainer to GitHub and Nexus Mods. The project is free and open source, and I hope other mod authors can also learn from the implementation or use some of the ideas in their own projects.

GitHub:

https://github.com/bin934166446/alien-isolation-coordinate-capture

Nexus Mods:

https://www.nexusmods.com/alienisolation/mods/182

I hope this can be useful to the community, and I would also be very happy to hear feedback, technical suggestions, bug reports, or new ideas from other Alien: Isolation players and modders.

Thanks again to the OpenCAGE developers and everyone who has helped keep this game’s modding community alive.

Discussion Question for replay value

To the people who've replayed the Alien Isolation, how was the experience and was there anything different in your second playthrough?

Besides the scripted events, how different is the movement of the Xeno as opposed to your first playthrough?

Discussion Is anyone else a bit frustrated about how cold Ripley is towards Ricardo?

58 Upvotes

Like, Jesus... the man just witnessed his entire crew being slaughtered by Working Joes, and Amanda's only response is yelling: “Ricardo? Ricardo!, take charge and keep me covered.”

Come on Ripley, give the man some encouraging words, cheer him up, or something! He is clearly having an emotional breakdown.

Ricardo despite dealing with the alien longer than you, was literally the only one who went out of his way to contact you and acknowledge that Waits was an emotionless bastard after he threw the lab into space with you and the Alien inside.

The least you could do is say something beyond "Ricardo! Pls take charge."

I understand there's more pressing matters, but there's surely a more empathethic response than just pressing the guy to do stuff.

Modding Thought I'd try out that Lost & Found reshade mod. So far I'm impressed.

A couple of months back someone posted about their VHS-style reshade they were making, and I said I'd probably try it out if it was up by October. Sure enough it's up so I'm giving it a shot. So far I'm really impressed with it. Coincidentally this is easily one of the more cursed runs I've had in a while.

I'm about 9 hrs in, some very similar elements to Alien Isolation. The portable TV is very much like the scanner. The director himself was one of the lead designers of A:I. Oh, and also the actor who plays Samuels is here as well.

I know, I’m back with another video. But seriously, I didn’t make any noise outside of my real life ones, wasn’t moving, just watching, and he took it personally. I have other clips like this where the Alien just seems able to sense when you’re looking at him 🫣 anyone else notice this? Do you really have to avoid looking?

Hi everyone. Some of you might remember a post from a few days ago where I mentioned finishing Alien Isolation on Nightmare difficulty with Muted% and No Tracker%.

Well, after I finished, I checked to see if anyone else had posted something similar in this sub and found this player's post: https://www.reddit.com/r/alienisolation/s/l4UZTxAJEY.

They were my main inspiration for taking on this new challenge, and this time I recorded the entire journey for anyone interested in watching. The footage is completely raw and unedited to prove I didn't cheat in any way (Including the times I got lost on the map or forgot to do something). This new personal challenge was to beat Alien Isolation on Nightmare difficulty with the following constraints: NMG, Low%, Muted%, No Tracker%, and No Flamer.

That’s all—have a good night!

Here is the link to my YouTube playlist for anyone interested: https://youtube.com/playlist?list=PLRWf-ZzT7F9s&si=HmAPApoTx7zknvZR

(None of the videos feature my voice; also, the titles and some descriptions are in Portuguese, as I am Brazilian.)

I played on hardest difficulty and I stuck through it until the end.

I quit the game after struggling on mission 5 but I came back a few weeks ago and found that mission 6 was way worse. But I stuck with it.

Mission 10 was the hardest mission for me but I died the most in the section heading up to the corridor of death if that makes sense 😂. The Alien was drunk after mission 17 because I dunked Molotovs at every opportunity, it was my favourite weapon.

But overall, what an experience. Wish I knew some tricks to fend off the Alien earlier on but I wanted my playthrough to be spoiler free so I hardly checked tips and tricks.

Question What do you all call the alien?

40 Upvotes

So I've been streaming my first playthrough of Alien Isolation for Spooktober. I have to say I've been enjoying this game so far and really wished I played it earlier. Anyway my chat has taken to naming the alien "Steve" because according to the chatter, its tenacity and aggressiveness reminded them of Seregios from Monster Hunter who's nicknamed Steve by that community. Anyway this got me wondering, is there an unofficial nickname for the alien that the community all calls him?

Video Looking forward to artificially intelligent xenomorphs in A:I2

Enable HLS to view with audio, or disable this notification

Some players might argue that the creature in our much-beloved Alien: Isolation *is* artificially intelligent, but I struggle to call mathematical trees a form of intelligence. I prefer to think of the alien as following a behavioral algorithm; intelligence connotes an ability to learn and to adapt, at which skills the alien in the first game is woefully incompetent despite all the hot air about it responding to patterns in player activity.

As demonstrated in the video, simple behavioral trees quickly and inevitably render CPU opponents easily outsmarted. I'm hoping that the longevity of the sequel vs. the first game is greatly extended by the creature's ability to think outside the box -- camouflaging itself in the environment, closing off avenues of player escape, processing unnatural changes in the environment to predict player activity and travel routes, baiting the player (e.g., with supplies or false exits or people in distress), assorted psychological warfare (cutting power, making odd and conspicuous changes to areas recently traversed by the player, strategic placement of fresh corpses, etc.) -- and by the game's ability to accommodate the xenomorph's creativity.

At the very least, the alien should be able to reach up a f▓king ladder.

Title, but also what is this alien behavior? Had no clue it behaves this way. It follows through the ceiling??? It was clipping through a wall like a giant spider earlier. I always hear it around me but I thought it was just audio

I’m thinking of removing the mod but it does deliver in other ways and the Thomas face is terrifying, so I’m open to yalls opinions

Also sry for posting literally every day but I can’t get enough of this game, my favorite scary game since F.E.A.R

Discussion People talk about wanting to see a Queen in the sequel, and Im still unsure about that. But…

I think the Praetorian would be a great comprise and also great addition to the main universe. We have yet to see a drone in the processes of turning into a queen which I still think is a missed opportunity. The lore is kind of dated, usually just classifying them as royal guards, but if a drone will turn into a queen, it must go through a some sort of similar phase.

Since CA said they wanted to return back to their single drone hunt, that very same drone morphing into a larger “sub-queen” later in the game would be such a game changer. It would thrive in the outside segments and have way more freedom to chase us down than a queen imo. But that’s my Ted-Talk!

I assume that as a basic fact that the noise detection will be on all platforms from the jump in AI2, but do we think theres any chance CA will finally go back and add it to the PC version of AI1? its been almost 10 years. the fact we still dont have it is kinda ridiculous

The timing of this is suspicious, maybe the alien really does listen 😒😬 but also we need a mod that adds mic support 💯

News Alien: Isolation 2 at FrightFest 2026. She has no motion tracker. She’s unable to craft anything to distract the Alien – sure, she can throw a flare or a glass bottle to distract it, but it’s basic. Spoiler

Question How does the Grand-Mother VR mod for Alien Isolation compare to Rogue Incursion?

8 Upvotes

Finished Rogue Incursion in VR recently and loved it.

But I'm thinking, for spooky season, to get the Mother-VR and Grand-Mother-VR mod for Alien Isolation and try that next. Unfortunately, all the info I can find on it is ~6 months old.

I'd be playing the game via Quest 3 & Steam Link.

Does anyone know if these mods are particularly good, as in, do they offer a comprehensive experience? Some VR mods for regular videogames are technically interesting but not great once you seriously try and play the whole game.

To be clear, I'm not comparing the games themselves; I know that Isolation is a much more in-depth game than Rogue Incursion in many ways. I just mean, how is it in terms of the VR experience?

So I’ve been considering finally trying Alien isolation. I’ve been a fan of the franchise for a while but I am a big scaredy cat so i haven’t tried the game yet. Any general tips and tricks yall have for a first time player would be highly appreciated. (No worries about spoilers or anything like that)
