Not sure how I feel about the Ripley face mask thing, but I guess it could be something that WY would up to if they finally got their hands on the Alien. And it does feel very Giger, more than anything in Prometheus did. There is some really interesting stuff in there. I especially love the pic of the Derelict inside the facility.
So I wonder if this would have been an alternate Alien 3, or if Ripley and Hicks were just stand ins to base the new concepts off of? I'm leaning towards the latter, but you never know.
It looks like everything is set inside of some interior artificial biological habitat. Almost gives me a bit of a Halo vibe in that regard.
I know this is unlikely to ever happen, but I would love if some more images and details were released. I am beyond curious.
