Overview
Swarmer is a compact 2x2 missile turret that fires homing rockets at both air and ground targets. It occupies a niche as a rapid-fire, short-to-mid range anti-horde and status-effect platform: its extremely high firing speed combined with selectable solid-ammo types lets it output very high DPS and apply nearly every solid-ammo status effect. Swarmer consumes booster fluid as a continuous "booster" at a high rate and fires one missile per ammo unit; it is most effective when paired with liquid turrets (

Swarmer’s ammunition options are distinct and each provides different damage profiles and status effects:
Pyratite: 12 direct damage, 45 area damage with a 2.5-tile radius, 5× ammo multiplier, homing, applies
Burning for about 8 seconds. Pyratite is the cheapest to produce and cleaves through groups quickly when combined with Oil- or
Slag-based liquid effects, but Pyratite stored in destroyed containers will explode and start fires.
Blast Compound: 10 direct damage, 45 area damage with a 3.7-tile radius, 5× ammo multiplier, homing, applies
Blasted. Blast Compound is strongest against dense swarms because of its wide blast radius and benefits from Cryofluid interactions (
Freezing/Blasted combos). Stored Blast Compound is also explosive if containers are destroyed. Surge Alloy: 18 direct damage, 35 area damage with a 3.1-tile radius, 4× ammo multiplier, homing, inflicts
Shocked (lightning strikes: 2× ~10 damage). Surge Alloy produces the highest sustained DPS when fed rapidly and does not cause explosive fires when stored, making it safer in Vaults/Containers.
Key mechanical notes and history carried into current behavior:
- Swarmer fires homing missiles and changed to consume 1 ammo per missile (instead of per burst) in recent updates, increasing ammo drain proportionally to its high fire rate. Ammo multipliers remain large (4×–5× per item), but the turret still expends ammo very quickly.
- The turret’s booster consumption is 18 units/second and boosters provide large temporary fire-rate multipliers;
Water boosters grant about 160% fire rate and Cryofluid about 235% fire rate under current values, making booster supply a major factor in peak DPS.
- Swarmer’s compact build and fast construction time make it well suited for temporary or forward defenses, but it performs poorly against heavily armoured targets because its damage is concentrated in explosive/area forms and many hits are subject to armor reduction.
Practical usage and strategy:
- Use Swarmer in batteries with mixed ammo to capitalize on its ability to apply every solid-ammo status effect; this flexibility allows combos like Burning +
Melting/
Tarred or
Wet + Shocked/Blasted depending on chosen ammo and accompanying liquid turrets. - Because of the very high fire rate and one-ammo-per-missile behavior, provide large or fast ammo production (dedicated conveyors, magazines, and refill lines). Without steady supply, Swarmers will deplete ammo quickly.
- Store Pyratite and Blast Compound carefully: both can explode if their storage blocks are destroyed. Surge Alloy is safer to stockpile.
- Swarmer is less effective versus high-armor single targets; prioritize it for crowd control and status applications.
- The turret is resistant to straightforward avoidance due to homing missiles and long effective range; to counter Swarmers, destroy ammunition logistics (conveyors/sorters), attack from paths that bypass defended lines, use long-range units that outrange the Swarmer’s area, or employ
Zenith-level bombing where available. Units such as
Fortress,
Minke, and
Bryde can outrange or threaten Swarmers in favorable sector layouts.
- A small practical detail: the Swarmer’s projectile sprite is noted to resemble the Malis logo.
Swarmer is an advanced, highly versatile defensive option when supplied and positioned correctly; its main trade-off is heavy resource and booster demand and relative weakness versus heavily armored single targets.
