It's an adventure game but it will be direct control(keyboard/gamepad, etc) instead of point & click. It will consist of multiply stories, puzzles, and character interaction. This title started out as an action title and a mixture of Mafia, Max Payne, Resident Evil, Silent Hill, etc but has evolved into a more pure adventure. It'll be more like The Twilight Zone or The Outer Limits than a straight up horror show, now. It'll still maintain the black & white palette and still be set in the 1930s/40s.

That should save you a lot of reading.

Oh, if you want to learn how to do nice weathered walls/floors, then get yourself a copy of Max Payne 2. I learned a lot from those levels.
