Custom models made by me (A lot of them!)
Unique and self-made jumpscares (realistic ones)
Original story Different endings
A lot of custom textures
Un-Expected flips in the story
Different objectives and situations
Very well treated lights, atmosphere, etc.
New types of puzzles
I'm not willing to put so much new things like a total conversion, but there will be never seen things. For example, a lava river, or a modern lab.
But i'm not going to say more. The only thing: keep an eye on this!
