Flood in Multiplayer, Halo 2- Need some help.

[o0stereo0o]

Im trying to make a good working flood skin for my map and I cant seem to get it perfect.. I finally got it so it doesnt freeze when I shoot it, but I cant get it to be able to crouch correctly or show weapons correctly. Need some tips or a tutorial on how to get this working 100%... need to know what to replace to make it so I can just change the SKIN of the thing and not all of the other jazz (tried model).
