Or anyone else who wants to tackle these.
I downloaded a crap ton of extracted models and textures from Bioshock from facepunch.com before they locked all the forums from non-members. If anyone would like to download these and poke around with them in whatever meshing program they prefer, please be my guest! I've been meaning to get back to these myself.
Warning: These are pretty big .rar files.
