The Harpoon Coil-Rifle is a Handheld Ranged Weapon in Barotrauma.


The Harpoon Coil-Rifle is a two-handed long-range medium-sized weapon. It fires Harpoons at a high velocity. It is an upgrade over the Harpoon Gun as it has a 1.7x damage multiplier, but has to have a charged battery in order to shoot. The Harpoon Coil-Rifle is effective both on board of the submarine and underwater. Upon hitting something, Harpoons may become lodged in the target (Note: This does not apply to the Explosive Harpoon) and can usually be recovered and reused. This property (plus the small material cost of the ammunition) makes the Harpoon Coil-Rifle a very cost-efficient weapon and that combined with the increased damage makes it proficient at stopping even some more dangerous denizens of Europa, such as Mudraptors or Tiger Threshers. However, just as its weaker counterpart, it can easily be overwhelmed by big groups of enemies due to the slow fire rate.

It can be crafted by a Security Officer with the Boarding Party talent unlocked, or alternatively can be bought on Outposts with a difficulty of at least 30.


The Harpoon Coil-Rifle is held with both hands and must be loaded with a Harpoon, an Explosive Harpoon, a Physicorium Harpoon or Ahab's Spear to be used. As with all weapons and tools, using it is done by holding the Right Mouse Right-click to take aim, then by Left Mouse Left-clicking to shoot/use.

  • It has a single slot for ammunition which can contain up to 6 Harpoons.
  • Unlike the regular Harpoon Guns, they require power to function, a single Battery Cell provides enough power for 12 shots, and a Fulgurium Battery Cell for 24 shots.
  • They have to charge for 0.25s before firing, to compensate their reload time is decreased to 1.5s, making their fire rate the same as a regular Harpoon Gun.
  • Fired Harpoons, other than Explosive Harpoons may be picked up as any other item with Left Mouse Button by default and reloaded into the Harpoon Coil-Rifle.
  • Shot harpoons have a rope attached to them, which reels any hit target towards the player. The rope snaps automatically 1 second after the Harpoon is fired if not attached to a target.
  • The rope will also snap automatically when the player ragdolled, shoot a new harpoon, or being too far from target.
  • Player can reel a target with a harpoon attached, as long as the target not being too heavy.
  • Like most two-handed weapons, the Harpoon Coil-Rifle has a Flashlight slot. The inserted Flashlight automatically turns on whenever the weapon is drawn.
  • It can be stored in the inventory, but not in Storage Containers.The same is true with Harpoons.
