This is a mod that makes the alien's sounds and movements quieter or silent. This mod requires you to rely more heavily on the Motion Tracker to avoid the alien. This does not completely remove the sounds the alien makes but removes all growls and snarls and stomps.
This is a mod that I've been working on to make the alien's sounds and movements quieter or silent.
Install by copying DATA file to your Alien Isolation directory.
This mod is inspired from Walter Valerie's "Silent Alien Mod":
The original mod created another empty ALIEN.BNK file with Wwise and replaced the original to get the effect of a silent alien. The problem I had with this is it made the alien completely silent to the point it didn't match within the game and felt too unrealistic so jumping in and out of vents in front of you the alien made absolutely no sounds and when hit with flame thrower, it also removed certain key scripted/environmental sounds produced by the Alien (distant screeches, in vents, etc) from the game that add to the atmosphere and immersion of the game. My method I edited the original BNK files and removed individual sounds as well as replacing additional related WEM files in the SOUND folder. All snarls, growls, grunts, and screams while the alien is roaming or spots the player have been completely removed. The alien still screeches in pain when hit with fire and makes vent noises and some movement sounds can be heard when it is very close by the player. The one drawback from my method and original mod is the Alien seems to be mostly quiet while also killing NPCs, though when editing I had not removed any of the unpacked WEM files that were remotely indicative of the alien attacking (screams/screeches/death encounters/etc), my only guess it has something to do with some code present in the original BNK.
Foot steps/running is currently completely silent as I have yet to figure out how to replace the sounds with edited versions, but I do have the ability to replace sounds with other original WEM files. I also have identified other sounds that I would like to add as optionally removed/replaced such as facehugger screeches and sounds made by the alien while up in the vents.
My hope is to repack a new Alien soundbank with muffled footstep and vent audio files. I was very thorough while going through all the WEM files listening to each individually and have played extensively and tested player/alien encounters and have not run into any weird issues or out of place sounds so far.
