Plan your next Sublight session

Our independent guide walks you through Sublight’s documented systems—combat, turrets, ships, progression, and platform tools—so you can make informed choices without relying on hidden mechanics or undocumented features.

01 / THE GUIDE

Firing‑Arc Observation

Place a wide‑arc autocannon and a narrow‑arc railgun on the same hull. Run a sector and note how enemy approach angles affect hit rates for each, highlighting safe versus risky arcs.

  • Test turret angles early to see how arcs cover incoming threats.
  • Watch enemy approach patterns to time shots within safe arcs.

02 / THE GUIDE

Upgrade Trade‑off Test

Build two ships: one emphasizing offensive passive upgrades, the other focusing on defensive upgrades. Play the same sector with each and record survivability versus damage output to see the balance impact.

  • Match high‑damage railguns with upgrades that boost accuracy.
  • Combine fast‑firing autocannons with fire‑rate upgrades for area coverage.

03 / THE GUIDE

Ship Ability Comparison

Select two unlocked ships that have different integrated abilities. Run an identical sector with each and compare how the abilities alter your tactical options alongside your turret setup.

  • Prioritize challenges that reward ships whose abilities complement your turret choices.
  • Experiment with alternative loadouts on a single hull to discover hidden synergies.

04 / THE GUIDE

Challenge Reward Log

Complete a series of in‑game challenges, documenting which ships, weapons, or upgrades you receive. Look for patterns that may guide future challenge selection.

  • Focus upgrades on the ship’s weakest defensive stat first.
  • Balance offensive and defensive upgrades to maintain survivability across sectors.

05 / THE GUIDE

Platform Feature Utilization

Enable Steam Cloud, finish a run, then reinstall the game on another machine. Verify that progress carries over, and compare leaderboard positions after each sector to assess community standing.

  • Enable Steam Cloud to protect your progress across devices.
  • Check leaderboards after each sector to gauge how your build ranks.
