Sublight Missile Build: Range, Explosive Damage, and Coverage
A practical Sublight missile build guide covering range, explosive damage, launcher volume, equipment choices, and keeping coverage against swarms and bosses.
Build missiles around range, explosive damage, enough attack speed or launcher volume, and mobility that keeps targets inside useful arcs. Missiles are forgiving because they continue toward targets, but a missile-only setup can struggle when dense swarms and large threats overlap. Do not sacrifice all coverage just to maximize single-projectile damage.
Core priorities
| Priority | Why it matters |
|---|---|
| Attack range | Lets launchers engage earlier and stay productive while you maneuver |
| Explosive damage | Supports the missile damage family and current autocannon crossover options |
| Attack speed / launcher volume | Prevents a high-damage build from feeling empty between volleys |
| Projectile speed | Improves practical hit timing on moving targets |
| Mobility | Lets you keep favorable distance without surrendering firing arcs |
The failure mode: too few missiles in the air
If large targets absorb each volley while smaller enemies close the gap, the run needs more coverage or firing volume. A missile build is not just “explosive damage.” It also needs sufficient coverage and firing volume.
What the patches changed
Patch 0.17.4 changed the Tier 3 missile launcher to feel like a direct upgrade and noted that swarm launchers would become a separate tree. That is a strong reason to avoid treating every missile-type launcher as the same tool. Compare behavior and firing pattern, not only the damage card.
Decision rule
If a choice gives you more damage but reduces the number of targets you can pressure, take it only when your current loadout already has enough lane coverage. If the screen is filling faster than enemies die, solve volume first.
Set the missile run up before the first cache
Use the three starting equipment slots added in 0.20.02 to support the way this missile hull actually handles. A movement choice can keep a firing lane open; another offensive choice helps only while launchers can keep working. This is a planning tradeoff, rather than a prescribed three-item set.
Weapons can be merged mid-run for increased damage since 0.20.0. When a duplicate appears, inspect the merge choice before assuming a new family is the better upgrade. Keep enough coverage for small enemies while a heavier target absorbs the volleys.
For pirate events, retain an escape lane and movement equipment for chains. Their run-currency chest can pay for the next useful choice, but it is not a specific missile reward.
