Quick question about co-op

#1Bigj089Posted 2/6/2013 9:51:59 PM(edited)
So, I found out recently there are co-op only areas, or at least one. Are there any parts unique to those that I cant find in singleplayer? Thanks in advance.

Well I figured that, but are there any unique weapons parts that can only be found using co-op? Or can you find them all in SP as well?
