Flamethrower turrets work similarly to the flamethrower, setting enemies and the ground on fire and doing damage over time. Unlike gun and laser turrets, they have a limited firing arc, and should therefore be placed at choke points or behind walls. They can use crude, heavy, or light oil as ammunition, which must be provided via a pipe connected to the turret. Flamethrower turrets gain a damage bonus depending on the type of oil supplied to them. This bonus is multiplicative, it stacks with the bonus damage from research.

Ammunition	Effect
Crude oil	100% Damage
Heavy oil	105% Damage
Light oil	110% Damage

Unlike the laser and gun turrets, flamethrower turrets do not have a instantaneously hitting projectile, instead firing a stream of flame directly at where the target was at the time of firing. This means that they have a tendency to miss the targeted biter in an attacking group, instead hitting the ones behind.

Flamethrower turrets are very powerful because biters and spitters do not have fire resistance and the total 3000 damage dealt to ignited enemies is a guaranteed death sentence for almost anything in the game. An enemy unit is ignited if it is hit directly by a flame stream. Flamethrower turrets will target the closest non ignited enemy and then once all enemies within range are ignited they will target the closest enemy.

The bonus technologies and fuel damage bonus for the flamethrower turret improve the contact damage and damage dealt by fire on the ground. The bonus technologies also affect the damage dealt to ignited enemies, which lasts 30 seconds and deals 100 damage per second without upgrades.

While it is not apparent from the damage bonus descriptions, the flamethrower turret benefits from the damage bonus for the flamethrower turret and the damage bonus for flamethrower ammo, applied multiplicatively, e.g. with the first level of refined flammables it receives a +44% bonus, not +20%, with all pre-space upgrades it receives +576% damage, not +160%. This is because the flamethrower turret is defined as using "flamethrower" type ammo and it allows the damage output of the flamethrower turret to keep up with laser and gun turrets, which also benefit from two or more separate upgrades.

Flamethrower turrets create fire on the ground which lasts 2 seconds by default. If the turret keeps firing at that spot, the size of the fire increases, it will last up to 30 seconds and its damage is increased up to 6 times, depending on how long the turret keeps firing at that spot. Multiple flamethrower turrets firing at the same location do not cause the fire to intensify faster as there is a 4 tick cooldown between intensity increases, while even a single flamethrower turret fires every 2 ticks.

Gleba

Gleba does not provide access to crude oil, light oil, or heavy oil. However, flamethrower turrets can still be used - either by importing barrels of oil directly, or by importing a small amount of heavy oil and using Coal liquefaction.

Vulcanus

Using flamethrower turrets is pointless - local fauna has 100% fire resistance.
