The Boarding Axe is a Melee Weapon in Barotrauma.


The Boarding Axe is a two-handed melee weapon. It has a reach of 1.55 meters, more than 3 times the range of the Diving Knife. In addition to this, it inflicts the highest amount of Lacerations of all melee weapons and has an extremely high Severance Chance. These properties make it the strongest melee weapon that does not require talent-specific builds.

It is very effective against any small Creatures given that unarmored ones like Crawlers are likely to be killed in a single strike to the head due to raw damage, and armored Creatures like Mudraptors are liable to get their limbs cut off very quickly. It also possesses significantly higher structure damage than most other melee weapons, making it possible to cut through a submarine's or wreck's walls a lot faster than with a Plasma Cutter.

It can be crafted by a Security Officer with the Boarding Party talent unlocked; it cannot be bought.


The Boarding Axe is held with both hands. 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.

  • Its extremely high severance chance makes it very probable to cut off limbs or entire chunks of armor of Creatures, making it possible to often kill them in one hit if their head is severed.

Damage Values

When comparing to knives, note that knives are one-handed and can be dual-wielded, effectively doubling DPS for most purposes.
