OpenCAGE VS pk3DS

Direct link to the github page

A programmer named Matt Filer has created a program to see the innards of the behavior tree of the alien. OpenCAGE. https://github.com/MattFiler/OpenCAGE It's an open source program to read the game files. CAGE stands for Creative Assemble Game Engine which is the programming interface that was used by Creative Assembly. Using OpenCAGE it has been found that if you have flamed the alien at any point during the nest area it will either set a vent ambush or it will drop and rush you as you pass the vent. So there is an RNG + scripted drop in that exit area depending on your actions.

I have no idea about VR but that sounds like a scaling thing in the VR. Also, as I said OpenCage which is a mod tool for the game enables some settings inside the game: https://github.com/MattFiler/OpenCAGE Mostly this is for modifying the game environment and behavior tree but there is a configuration menu edit option in configuration editor > Graphics Settings Editor. Enable Stereo mode. Oculus Rift, 3D TV and Anaglyph.

You can use this software to mod the game and the alien https://github.com/MattFiler/OpenCAGE

There is a full mod suite called OpenCAGE. It was designed from the ground up for making modifications to Alien Isolation: https://github.com/MattFiler/OpenCAGE

You might be able to build it with those encounters with pk3ds if a hack including all exclusive wild encounters doesn't exist.

Maybe possible with pk3DS or you can try editing your save file with PKHeX.
