Finished it last night about 2am
lol, well 1am really.
Couple of gripes, found the combat really boring in all honesty played the whole game using nothing but the shotgun and sniper rifle as i found no real reason to use anything else, same with the vigor's, lightning and devils kiss were all i needed. Played it on normal might be better on hard or 1999 mode. The plot twist sadly worked out before i actually got to the end so was like oh so it was that.
As for the good parts loved the city and view even if the floating buildings made me sea sick
lol. Elizabeth was extremely well acted and believable in most cases, by far one of the best single player game sidekicks up their with Dog and the Companion cube.
Personally I'd say it was a 8/10 as it lacked some of the punch of the original bioshock and ferocity, for example the big daddy's were something to be feared and you had to make sure you was armed to the teeth to take one out in contrast found the patriots and handyman cannon fodder.
