They 'could have' used Victor to describe Frankenstein... but they didn't. They chose a different name for the old mad scientist.  Instead they chose it for one of the warriors.
Oh, in the Necromaner's Area, there are a lot of portals you jump into and out of.  The description reads "..hundreds of mirrors that can transport you anywhere; such is the so-called 'Apreture Magic' from the Necromancers".  It's a direct reference to Portal from the Orange Box, as the name of the technology for the Portal Gun comes from "Aperture Science". xD
