Sublight Weapon Categories & Damage Types Explained

A current Sublight weapon-category guide covering rapid fire, railguns, plasma/pulse, autocannons, missiles, barrage, strike craft, and elemental/status interactions.

QUICK ANSWER

Think of Sublight weapons in two layers: the weapon itself and the higher category/passive track that supports it. Patch 0.17.4 added higher-level weapon categories plus captain and upgrade synergies, while 0.18 moved autocannons to explosive damage and strengthened status-based elemental build options. Build bonuses should match the category your actual mounts use.

Why categories matter

Before 0.17.4, it was easier to treat a weapon as an isolated pickup. The category pass changed that. Captains and upgrades can now reinforce higher-level families, which makes coherent builds more reliable than collecting unrelated high-rarity guns.

Families seen in official notes and gameplay

FamilyCurrent useful note
Rapid fire / chaingun0.18 pierces up to attack range
Railgun / kineticLater pierces deal reduced damage
AutocannonMoved to explosive damage in 0.18
Missile / launcherTier progression and separate swarm direction were being developed
BarrageNow leads shots more accurately
Strike craftFighters, escorts and frigates have distinct behavior
Elemental/statusIgnite and Cold now stack

The safest rule for upgrade screens

If an upgrade text names a category you are not using, it is usually weaker than a lower-rarity option that multiplies the weapons already doing most of your damage. Build coherence beats card color.

Research choices: Mines, Scatter and pulse weapons

0.20.02 adds research options for Mines and Scatter guns. Match the actual weapon and research text to the bonuses you buy; a research addition does not make those families interchangeable with autocannons or railguns.

The earlier 0.20.0 update also added variants based on research selections. Its pulse change is distinct: all pulse weapons synchronize into one attack, using the highest-level pulse weapon as the timing reference, while multiple pulse weapons produce multiple attacks in the same wave. Use the Armoury guide for unlocks and the target-priority guide for which threats your mounts attack.
