Nearly done with Bioshock again and on track for a few more achievements.
Should be able to get Weapon Specialist, Little Sister Savior and Historian.
Will possibly miss Research PhD, Seriously Good At This (as the game has to be completed on Hard) and Brass Balls (use no Vita-Chambers).
Really enjoyed playing it through again, watching out for all the environmental intricacies and subtler plot elements.
Edit: Managed to get the 3 expected achievements and as a surprise bonus, Research PhD, as I went back through the whole game as a Big Daddy.
