Shoot sound

Cannon sound



  • The magazine capacity of this weapon is shown as 500 in the description, though when bought, it is 350 only. The rocket damage stated in the description is also far more powerful than in game.
    • As such, this is one of the weapons that are suspected to be nerfed right before release.
  • The shoot sound is quite similar with TURBULENT-7.
  • The rocket sound is quite similar with X-TRACKER.
  • There is a bug with the rocket launcher view model. It does not appear when you switch to some certain weapon (ex. Bear Fury MK-3). You need to switch to other weapon and then switch back to make the rocket launcher appear.
  • It is one of the weapons that is buffed due to player complains of it being to weak, along with the aim FX is reworked for simplicity.
