so its basically:
-enter a room. look around for things to do.
-it could be either hack a door, wield behind you or open a path, pick up weapons, documents, different stuff that could come handy. maybe find a guy and get him to help you out?
-get the hell out of there before aliens get you!
-wrong path. you died/got facehugged. try again!
-you arrived at a big room. make a stand here Y/N? if so, you have limited time to set up sentries, mines, wield doors, etc.
-corporates! now that you got backstabbed and left there to die, find a way out of there/ eliminate all evidence to keep the company from getting the alien(please dont do this, its the most overused plot ever).
i loved the demo btw. im willing to lend some ideas
