In Sublight, you command a stellar battleship and fight through multiple deadly sectors, carving through escalating waves of enemies from rogue rebel fleets to ravenous alien swarms. Blast enemies to salvage materials, level up your ship, and combine a vast pool of turrets with dozens of passive upgrades to build the ultimate warship.
What’s in Early Access
Multiple deadly sectors, with weekly rotating level modifiers on the way.
Each with integrated weapon systems, abilities and alternative loadouts.
From shredding autocannons to piercing railguns, plus a set of build upgrades.
Rebel fleets and alien swarms, plus multiple bosses with weapon drops.
Completing in-game challenges unlocks even more ships, weapons and upgrades, and Steam Leaderboards let you compare runs with other captains.
The Roadmap
Early Access is just the start, and Codebrew has already laid out a full content roadmap running through Q3 2027:
| When | What’s Planned |
|---|---|
| Sept 15, 2026 | Early Access launch: 6 levels, 9 ships, 16+ weapons, 2 enemy factions and multiple bosses. |
| Q4 2026 | A new enemy faction, new ships and weapons, more builds and balance changes. |
| Q1 2027 | More unique boss drop weapons, enemy flagship hunts and new mission types. |
| Q2 2027 | A refreshed campaign built around an XCOM-style threat map, with longer, connected narrative missions, expanded factions and more research options. |
| Q3 2027 | Community-voted content (players choose new ships, weapons and builds via Discord polls), plus mod support and achievements. |
All roadmap content is Early Access and subject to change.
What Players Are Saying
Players have rated Sublight Very Positive on Steam, with more than 90% of reviews recommending it. Fans enjoy piloting a lumbering battleship that has to swing its broadside toward the enemy, the variety of ships and builds, and the new bosses and their weapon drops, and one points to an active Discord and a year-long roadmap. One player summed it up as Vampire Survivors in a sci-fi setting.
The main criticism is content, which is common for a fresh Early Access launch. Several players found the current six maps too short or a bit repetitive, while one felt the combat lacks impact. Several of them still recommend it, and are keen to see what the updates bring.
