You will have to have some time stretches in there - like having sections of playable flashbacks because at the time of Kashmir, Ryan didnt have alot of 'heavies' and more things like that were later developed to fight the Splicer army Atlas built (and the security machines etc..)  You can have the player go around in that environment for a while and then have it contrasted with what happens later.

Also you would have your main character caught in the middle between the two sides (your heavy hitters also on that side...)   Your character just finding his daughter would not have concerned Ryan that much with the 'war' situation ongoing. Having people murdered in the streets by Altas's minions is pretty dark a situation already  (you are no longer in any 'normal' situation as it might have been before Kashmir)

Which side has her (Atlas has to make ADAM too), is she a Little Sister with a  Big Daddy or in a ADAM Farm of Fontaines, or somehwere else... Your character sneaking around past the security measure, past Atlas's thugs, etc... Various criminals are taking advantage of the chaos, supplying more inetersting situations.
