Sniper Rifle-Replaces the Disruptor with an Sniper Rifle (doesn't matter what Rifle to use for the model)
the missle launcher into a nuke launcher (don't use too much efx with this or bad lag x.x)
this may be too hard but the Repeater gun replaced by a some gun with a pro tube (or Rifle Grenades).
@ EurOs wasn't there Nazis in Crystal Skull also? Cuz there should also be models of em too.
