  • As with all sonic emitter modulations, it is necessary to install the Blind Diode Jefferson's personality chip before this remodulation can be applied to the sonic emitter.
  • All cyberdogs are affected by the additional EMP damage done by this weapon.


  • pcIcon pc ps3Icon ps3 xbox360Icon xbox360 The knockback effect modifies the script used by bighorners in order to make it work with the sonic emitter. This modification completely nullifies the effect when it is used by bighorners. [verified]

  • xbox360Icon xbox360 In some playthroughs, Audio Sample - Gabriel's Bark will not spawn in any of the digging spots and there is no way to get the holotape to re-spawn through a previous reload or otherwise. [verified]
