  • The Bronco Prime's high damage, high spread and high pellet count (with Mod TT 20px.png Barrel Diffusion) make it a good crowd thinner and control tool, particularly against the Infested.
    • Using Mod TT 20px.png Seeker is recommended to increase its capability against large groups of enemies.
  • Mod TT 20px.png Gunslinger (or Mod TT 20px.png Lethal Torrent) and Mod TT 20px.png Quickdraw may be valuable due to the low rate of fire and reload speed, to increase the time spent shooting.


  • The Bronco Prime has a non-static model, the barrel section rotates clockwise when fired and whilst reloading.
  • The Bronco Prime's gold parts can be recolored as of Update 15.13 (2015-02-05).


Patch History[]

Update 27.2 (2020-03-05)

Greater than 100% Status having meaning

Shotguns have a unique Role here based on a very patch-work history with how they interact with Status Chance. A Shotgun that shoots 99% Status Chance would give you 35% (roughly) status per pellet. 100% Status Gives you 100% Status per pellet. This huge jump in performance happens with just a 1% gain - why? Well, to answer that we have to look at our choice to make what the UI conveys reality. It would feel broken to shoot a Shotgun with 100% Status and not see a perfect spread of Effects. In reality, to make Status consistent we have to treat Shotguns as a special case.

Shotguns as a special case means we have buffed the Status Chance of all Shotguns by x3 or greater. The UI now behaves to show the reality that you are determining Status Chance per pellet.
