how about bioshock 3 is prequel and you play as a scientist who is being attacked by splicers and such and is forced to do the same to survive, then the game takes place with you trying desperately to escape, which can end in three way 1) you pull it off and make it out in one piece 2) your killed in the attempt 3) (probly the coolest) all the plasmids and genes you've spliced drive you insane and you turn into one of the huge numbers that are in bioshock one and 2. admittedly this would cause some balancing issues because it would mean your only as powerful as the numerous cannon-fodder enemies in the previous games but it could be countered with theres a lot less enemies to deal with and you end up having to sneak around a lot.
tell me this wouldn't be awesome!
