Good question!
I don't see this game being revolutionary, at least not with what has been shown. Here are things I can see happening such as: • Larger rooms, some of them perhaps being very large like some immersive sim maps. This might explain the HUD having a compass. • Another HUD element is a notification icon next to the radar, and I have to wonder if it'll be used only for the hint system, or if we will get calls, or perhaps, sidequests. • The central mechanic of the game being some form of localized time travel thing. Too many hints as to not be case. • MouseCon aiming, this has to happen. • Too much of the demo shown resembles MP3, which is definitely not my cup of tea, but that doesn't really say a lot about the rest of the game. I doubt they went through the effort to color coding enemies and allies on the radar just for the tutorial.
