The Flamer (also known as the Flamethrower) is a handheld weapon added as part of the Saints and Sinners update.


The Flamer is a short range weapon, which spews a constant stream of flames, fed by Welding Fuel. For obvious reasons, the Flamer only works in a dry area (attempting to use it underwater will result on a stream of harmless bubbles). As a flamethrower, using it will start Fires in the Submarine, which should be considered whenever using the Flamer. The Flamer needs a source of fuel to function Welding Fuel Tank.pngWelding Fuel Tank and Incendium Fuel Tank.pngIncendium Fuel Tank are both valid sources of Fuel (with Incendium fuel tanks lasting about twice as long).

The Flamer deliver a notable amount of Burn damage (and a small amount of Burn to the user), further increased by the Fires that it will start. As side effects, the Flamer will consume Oxygen from the room it's used in, and will stop functioning when the oxygen level drops below 10%. Additionally, fires can cause spare Fuel Tanks to explode, even when they're inside a container. Caution is advised when using the Flamer, and a Fire Extinguisher is greatly recommended for safe handling.

Unlike most weapons, the Flamer does not cause any Stun nor does it have any stopping power, while it deals a notable amount of damage in a short time, it does nothing to prevent Creatures from getting close enough to attack the user.


The Flamer is held with both hands and must be loaded with Welding Fuel Tank.pngWelding Fuel Tank or Incendium Fuel Tank.pngIncendium Fuel Tank to be used. As with all weapons and tools, using it is done by holding the Right Right-click to take aim, then by Left Left-clicking to shoot/use. Holding down Left lets the user fire continuously until fuel runs out. While Welding Fuel cannot be refilled, it's plentifully available on most Submarines, so ammo should not be a concern.

  • Welding Tanks can sustain a Flamer for around 17 seconds, Incendium Fuel Tanks can sustain the Flamer for 40 seconds, and both will only last 11 seconds if the user's Weapons Skill is below 20.
  • Despite being considered a Weapon, internally, the Flamer is actually a Repair Tool (like the Plasma Cutter and the Welding Tool) which does not interact with Structures, and with a chance to start Fires.
