To add to this:I do recommend buffing the FOV some.
C:\Users\<windows name>\AppData\Roaming\Bioshock2
edit the user.ini under [Default]
NumPad0=InjectBioAmmo
NumPad1=SetFOV 90
You can bind to other keys but I just used those two. Bioammo is your plasmid replenishment. This is what I did to play Minervas Den.
edit: if you are playing widescreen you might want to try a lower number (im on 4:3 so it scales differently).
