The Halibut Cannon is a Revengeance Mode-exclusive Pre-Hardmode gun obtained incredibly rarely from any enemy in the Abyss, with a somewhat higher chance to drop from the biome's mini bosses and a guaranteed drop from the Adult Eidolon Wyrm. It fires out between 25 and 35 bullets per shot that slowly spread out, while only consuming one unit of ammo. While the default base damage is 12, the total bullet damage is halved before defeating the Wall of Flesh. This effect is calculated after all damage boosts and the additional damage provided by the ammo. Additionally, its base damage scaled after defeating the following bosses:

After defeating all the above bosses, the Halibut Cannon gains 345% extra damage, totaling 53 base damage.

Its best modifier is Unreal.


  • When using Acid Rounds or Ichor Bullets as ammo, its damage is reduced by 15%.
  • The drop rate of this weapon is unaffected by the Defiled Rune.
  • This weapon is intended to be excessively powerful, being able to plow through most of the bosses in the game with ease despite being available Pre-Hardmode.
    • In addition, this weapon can quickly demolish groups of enemies and is still powerful even after defeating the Moon Lord.
  • Because of its low base damage, the Halibut Cannon is even more effective when paired with equipment that provides armor penetration such as the Reaper Tooth Necklace.
  • With the exception of Luminite Bullets, piercing bullets are not effective when using the Halibut Cannon as only one bullet will strike per salvo.


  • This weapon is a reference to the late game critic TotalBiscuit, previously known as TotalHalibut, as indicated by the presence of stereotypical British attire on the weapon's sprite.
  • Halibut is a typical name of fish from the family of right eyed flounders.
