Gunboats are special enemies found only in Port Tortuga. They do not have an encyclopedia entry.


A Gunboat spawns from the entrance west of the northern Pirate Watchtower. It will then proceed to move around the tower to the entrance east of it, while every now and then stopping to fire on your troops.

Gunboats have unlimited range, though they do not linger to kill all your soldiers like other ranged enemies. Instead, they only fire several volleys before leaving. Letting a Gunboat leave is not considered a leak, and thus does not reduce lives, but also does not grant the Gunboat's bounty. However, they should be killed whenever possible because of their huge bounty.

The damage is split down the middle, dealing half True Damage and half standard physical damage. Therefore, they can easily kill soldiers, even armored heroes if you're not careful.

Templars with Toughness upgrade and Boatswains can take 4-5 shots. Although Gunboats cannot directly target Ashbite or Bonehart, cannon explosions do damage the dragons.

Gunboats spawn very frequently in Iron Challenge mode: when a Gunboat leaves, another spawns after just a few seconds; sometimes there are even three Gunboats spawning next to each other. Gunboats do not appear in the Heroic Challenge.


It is waste of gold to buy Pirate Watchtower's upgrades in order to kill Gunboats in Campaign mode. The tower fires slow and takes a long time to kill it even with all upgrades. A well-timed Rain of Fire can quickly get rid of Gunboat.

  • Gunboats can be abducted by Sha'tra, however since there apparently is no animation for a Gunboat being abducted, it will simply vanish into thin air.
  • Similarly, when a Gunboat is eaten by Ashbite, it still shows blood and gore, as if the boat was actually an organic creature.
  • Gunboats are the biggest regular enemy across all three Kingdom Rush games.
  • The missiles sound different in the Steam version, from launch to impact, the latter of which is not the traditional artillery explosion sound effect like it is in mobile..
