  • This weapon counts towards Gun Runners' Arsenal Challenge and Overkill.
  • This is the only GRA weapon to accept standard weapons mods.
  • This is the only GRA version of a weapon that was made solely for the purpose of accepting new ammo types. This was because the standard Fat Man can only fire one type of ammo and thus lacks an unloading animation.
