Turrets

Defensive and offensive combat units — gunner, sentinel, breach, and launcher.

Every turret except the launcher faces in one of 8 directions. Ammo must be fed to turrets via conveyors, from any direction except the direction the turret is facing. Diagonal turrets can be fed from all four sides.

Ammo-based turrets can hold up to one stack of one resource type and only accept incoming resources when completely empty.

If a tile containing both a building and a unit is hit, both take full damage.

Gunner

Has a vision radius of √13. Can only target the closest non-empty tile in the direction it is facing. Using refined axionite as ammo deals double damage.

Property	Value
HP	40
Base cost	10 Ti
Scaling	10%
Damage	10 (20 with refined axionite)
Reload	1 round
Ammo per shot	2
Vision r²	13
Attack r²	13 (same as vision)

Cardinal

Diagonal

Sentinel

High range, low damage support turret. Can hit all tiles within 1 king move (Chebyshev distance) of the straight line in its facing direction, within vision range.

Using refined axionite instead of titanium as ammo adds +3 to the action and move cooldown of any unit directly hit — acting as a stun.

Property	Value
HP	30
Base cost	15 Ti
Scaling	10%
Damage	20
Reload	4 rounds
Ammo per shot	10
Vision r²	32
Attack r²	32 (same as vision)

Cardinal

Diagonal

Sentinels with refined axionite ammo are extremely powerful — a +3 cooldown stun can completely shut down enemy builder bots.

Breach

Very high damage with splash. Attacks in a 180° cone in the facing direction.

Property	Value
HP	60
Base cost	30 Ti, 10 Ax
Scaling	10%
Damage	40 direct + 20 splash (8 surrounding tiles)
Reload	1 round
Ammo per shot	5 (refined axionite only)
Vision r²	10
Attack r²	5

Cardinal

Diagonal

Breach turrets have friendly fire on the splash damage (8 surrounding tiles). They do not damage themselves.

Launcher

Picks up and throws adjacent builder bots to a target tile within range. The target tile must be bot-passable. Unlike other turrets, launchers have no facing direction and do not use ammo.

Property	Value
HP	30
Base cost	20 Ti
Scaling	10%
Reload	1 round
Vision r²	26
Attack r²	26 (same as vision)
