What about some of the Splicer monster concepts in the book, which was what Colin Fix and 2K Marine seemed to be working into BioShock 2 before the initial idea was scrapped. The pages for concepts seem to go on from 18-26, with 19-22, 24-25 as the final revision, and 24 and 26 were reusing the Brute as it.
