I personally can't see the appeal, and this is coming from someone who likes old first person shooters. I don't see much information about what kind of game it'll be aside from the PR fill, and the lack of any in-engine shots is alarming. The projected Winter 2018 release also isn't a good sign: most Kickstarter campaigns drastically underestimate how long their project will take.
I predict an underwhelming product even if their funding goals are met.
