The Pulse Laser is a Submarine Weapon in Barotrauma. Similar to other Submarine Weapons, it requires a loader to be linked to it for ammo. It is the only Turret to fire a raycast attack, instead of a projectile attack.


Pulse Lasers shoot lasers that deal burn damage to anything they hit, as well as some explosive and burn damage to enemies directly nearby.

  • It has a 1 second charge-up before each pulse and a 0.25s reload time after.

The Pulse laser is especially good for use with bots, as they possess perfect aim and will always hit the target with single laser (Tri-Laser Fuel is useless on them however, as they never consider extra beams when firing).


Like other Turrets, Periscopes are typically used to aim and fire Pulse Lasers. Firing Pulse Lasers draws power from their connected Supercapacitors, as well as ammunition from their linked loader. The position_in and trigger_in connectors in the connection panel must be wired to a Periscope's position_out and trigger_out connectors respectively.

Damage values

There are 2 types of Pulse Laser ammunition:
Standard: specialized for killing small or medium single target creatures.
Tri-Laser: specialized for spread-out crowds of creatures, as well as dealing close-range high damage on a single larger creature (such as Endworm once its armor has been broken).
