Modifiers are upgrades installed inside individual ship modules. They can improve a module's output, change how the module works, and create new synergies, and the launch post lists them alongside modules as the two tools that let you survive a run. Where they come from matters more than usual, because the two sources draw from largely separate pools.
What the Hull Rupture modifiers guide covers
A modifier is not a module and not a turret — it is something you install into a module to change that module. It can raise output, rewrite how the module behaves, or create a combination that neither part offers alone. That last case is the interesting one: modifiers are where an average layout becomes an absurdly efficient one.
Two separate pools
You can purchase modifiers in shops, or obtain them through narrative events — and the pools barely overlap. Some shop modifiers never appear in events, while most event modifiers cannot be purchased at all.
Random-event stars on the galaxy map are the main source of the event modifiers, so exploring is how you widen that pool. The travel events guide covers which stars produce them and how event choices get gated.
A worked example
A modifier that adds mushrooms to the Mineral Generator significantly increases Mineral output — but only while you have fewer than 10 units of Mystic Goo. So receiving it can push you into abandoning Goo production entirely and restructuring your economy around mining Minerals instead.
That is the shape of a good modifier: it changes what your ship should be, not just what it produces. When you find one, the real question is whether your current chain can be rebuilt around it, which is a production chain question.
How modifiers changed in the September update
The September 2026 demo update added new modifiers and reworked some existing ones so that they also affect turrets — giving the Reproducer the Eyes modifier makes all Beam turrets apply the Fragility debuff — while weakening unit-based ship defense, with the Cheat Code artifact nerfed as the example.
The demo's modifier pool skewed heavily toward economy and production. The full game adds many more that affect combat directly, especially those that improve your turrets, so a pool read on the demo will be out of date. The turret placement guide covers the weapon side of that shift.
Modifiers and artifacts are different pipelines
Artifacts are collected and unlocked as run-defining collectibles, while modifiers are installed into individual modules. The two come from different places and solve different problems: an artifact changes what a whole region of your ship is worth, a modifier changes one module.
The artifacts guide covers that half of the collection game, including why demo-era artifact unlocks do not transfer.
