Looking at that video, it seems more generic. However, I am willing to give it the benefit of the doubt based on how I loved the first one.
I just have a few concerns. They are, does it have re-playability on a level higher than the first one(Only one pass and done), and how does the multi-player stack up against other FPS type games.
Speaking of multi-player, I honestly believe Bioshock type games would benefit from a DoTA style leveling system for your person where you gain extra abilities as you play each map(new person to game would get leveled up to the point of the average level of said game to keep it balanced when new people join an already existing match). It just screams re-playability that way. At least for a while.
