If they ever make Isolation 2 I really hope they completely re-work the alien, the look of it but especially it's behaviour. It wasn't so much alien imo as it was a dinosaur stalking you ala the kitchen scene in Jurassic Park. I think it should be chilling and hiding in ceilings and walls, you know dangling from chains or crawled up between pipes, only reacting to your mistakes such as tipping over furniture or shining your flashlight directly at it for too long and then have it emerge creepily and slowly only to burst into extremely quick movements to close the gap between you and it. Also, the environments need to be darker and more reliant on you lighting up the environment with what you got.
