I went back to the project, this time with a bit more modding knowledge. The FIB agents have changed into lightly armored cops. Additionally, I added a few face models for cops, fat cops and changed the FIB car to the police Buffalo (mesh from TBoGT).
I am happy to accept advice on the further development of the mod, the most interesting ideas will be used in the third version of modification.
Have fun with my cops!
