Any proficiency on any gun

- So first off you need an Overkill Pro class.
- Make 2 Sniper or Shotgun classes and put either speed or damage on both of them.
- Next make a class with NO proficiency at all.
- Now start up the game, have the overkill class on and kill yourself and change your class to the other class you made.
- Simple as that, you now have what ever proficiency the overkill class had on any gun with no proficiency.
