The Soldier on the space marines

The Righteous Bison is a secondary weapon for the Soldier. It is a handheld retro-futuristic or steampunk-styled ray gun.

The weapon fires a slow-moving, unreflectable projectile beam that pierces targets in a straight line, at the cost of dealing heavily reduced damage to buildings. Each beam is able to hurt an infinite amount of targets, but its damage is reduced by 25% for each target penetrated. In addition, the beam can be used to ignite Huntsman arrows held by a friendly Sniper.

Like the Cow Mangler 5000, the Righteous Bison features a "Bison" bar in the HUD which serves as an indication of its ammunition clip. After the bar is depleted, it can be recharged through a reloading process in which a piston in the back of the weapon is pumped. It does not incorporate the traditional ammo reserve used by other weapons.

Enemies killed by the Bison suffer a distinctive death by vaporization: they turn black, hover in mid-air while surrounded by team-colored particles, and then disappear into ashes while a loud, distinct vaporization sound plays. Like backstabs and headshots, there is a 25% chance that opponents will perform a specific disintegration animation if killed in this way.

Weta Workshop held a panel at San Diego Comic-Con 2011 and handed out coupon codes to visitors that can be redeemed in Team Fortress 2 for a Genuine quality Righteous Bison.[1]

Unused content

  • There is a set of additional projectile particles, that are not used.
    • There is also an impact particle, though since the projectile just passes through the enemies, the impact particle is never seen.
  • This weapon contains an unused idle sound and an alternative projectile shot sound.


  • The attribute -34% clip size is missing.
  • Rarely, after a moment of not firing, the Soldier will automatically reload the weapon's clip, regardless of the player's auto-reload setting.
  • In the client view, while crouching, the projectile will appear to fire much higher than the weapon model.
  • When minimizing the game with this weapon equipped, the ammo portion of the HUD may disappear. Looking at the scoreboard may fix this.


  • The appearance of this weapon is based on that of 'The Righteous Bison - Indivisible Particle Smasher', which can be purchased from the online store at Weta Workshop.
