This Alien: Isolation mod has been designed initially for personal use and increases view, hearing, AI and damage caused by the enemies of the game. The alien with this mod will be searching in the ventilation ducts also used by you, will hear walking in an adjoining room, and will be alarmed just try to peek from a hiding place for a few moments in excessive. Some ridiculous hidings will not work anymore; for example between chairs or low objects, and hiding under tables and benches will be much less effective if you do not hide you well. Some other changes are: a realistic backpack that can hold a few items, the increased cost of crafting for medicament and equipment, more difficult minigames, the increase of flamethrower consumption, the damage against alien with some equipment and more. For installation, just download the archive below and unpack the contents in the game folders.
doing some testing with the mod, seems the alien now triggers much more easily in places it normally wouldnt trigger, like the systech spire when you go to trap the alien, the lobby with the people it shows up immediately and starts killing. also in the stair well for the first survivor mode mission (this is kinda neat, but i can see it being a problem in some areas).
The alien seems alot less predictable, but doesnt stray too far like in the unpredictable alien mod. For example, usually the first thing it does in the first survivor mission is walk straight past the intersection once you open the door, took awhile for it to do that with this mod.
some concerns are like the first segment is alien appearing outside of intended areas/ alien triggered in non-alien areas too easily. another thing i noticed with some survivor mode testing is a tendency for the alien to beeline for whatever vent you're in not too long after you enter it.
basically, pretty cool but not sure if i'll do a full playthrough with it as the base game stresses me out enough already lol. will also do further testing to check if this breaks the game or not. if i can figure out what the individual files do in this mod i might tweak it for personal tastes
