Fulgora's moon of puzzles. Ancient wrecks embedded in thick ice can seemingly be repaired, including a colossal nuclear reactor that could transform the possibilities on the surface... if you can get it working. Cerys is a complete and polished mod that does not modify the vanilla game in any way, so is easy to include in existing saves.
Mods introducing new content into the game.
Version: 4.11.0-4.11.3
Date: 2025-09-24
Info:
- These releases add support for Factorio 2.0.67, handling a breaking change in the Factorio engine. Players upgrading their client to 2.0.67 or greater will need to update Cerys to v4.11.
Features:
- Added new mod setting 'Undo tech price multiplier for Cerys techs', which can be used to restore Cerys technologies to their original costs while playing 'marathon' games with a tech multiplier.
Changes:
- Adjusted the space map position of Cerys around Fulgora to collide less frequently with other routes.
- Added Speed module 2 as a Cerys moon discovery prerequisite.
- Fulgoran cryogenics is now a trigger technology, so can be researched without being specifically selected.
- The Kofi toast now prints when the nuke is launched into orbit.
- Increased the number of charging rods built before triggering a performance warning from 250 to 400.
Graphics:
- New graphics for the Ghost charged particle maker.
- Improved graphics for the flowing lights on charging rods.
- Adjusted the appearance of minable resources when using high values on the map sliders.
Bugfixes:
- Fixed that the charging rod's GUI could briefly show on other accumulators in multiplayer games.
- Fixed that the radius visualization shown on player-crafted radiative towers did not extend fully to the edge of tiles 13m away.
- Fixed that upgrading the quality of the Fulgoran reactor did not consume the player's scaffold from their cursor.
Compatibility:
- Marked certain Bob's Mods as incompatible for now since they cause the player to get softlocked on Cerys.
- Marked Oarc Multiplayer Spawn as incompatible for now since the Fulgoran buildings on Cerys are associated to the 'player' force.
- Marked Janus as incompatible for now as this mod currently interferes with water tiles on Cerys by destroying their unique collision mask.
- Marked Automated Crushers as incompatible for now as this mod prevents Fulgoran crushers on Cerys from working.
Locale:
- German translation updated.
Version: 4.10.4
Date: 2025-09-18
Bugfixes:
- Fixed that the charging rod GUI was visible on other accumulator-type entities after visiting Cerys.
Version: 4.10.3
Date: 2025-09-18
Bugfixes:
- Fixed that the teleporter could occasionally spawn out of heating tower range.
Version: 4.10.2
Date: 2025-09-14
Locale:
- Korean translation updated.
Version: 4.10.1
Date: 2025-09-11
Bugfixes:
- Fixed a crash when building a previewed blueprint record.
Version: 4.10.0
Date: 2025-09-10
Changes:
- Concrete can now be placed on shallow water on Cerys.
- Fulgoran crusher wrecks no longer have a module slot (matching the repaired entity).
- The Neutron bomb item description now states the pressure threshold under which its behavior changes.

Optimizations:
- Performance improvements to heat pipe cooling on Factorio 2.0.64+.
Version: 4.9.4
Date: 2025-09-03
Optimizations:
- Improved the performance of charged particles.
Version: 4.9.0-4.9.3
Date: 2025-09-03
Changes:
- Breaking change: Charged particle deflection reverted to Cerys v3 (2 weeks ago). We realized a fundamental problem with long-range deflection: it makes the particles behave less like 'pinballs' and they thermalize faster. Due to time-reversal symmetry, thermalized particles are impossible to accumulate in any zone. v4 worked for basic farms, but was impossible to optimize without making the farm the size of the moon. We have however kept a modest version of evaporation at low speeds in order to buff non-trapping designs in relative terms. This is intended as long-term stable and is non-breaking with v3 bases.
- Breaking change (minor): Crafting radioactive modules now requires a radioactive isotope (U235) instead of chips.
- Ghost charged particles now react to ghost charging rods.
- The base of charging rods now always glows with the polarity color, making it easier to infer their polarity when uncharged or partially charged.
- U235 can no longer be recycled prior to unlocking waste reprocessing (as with U238).
Bugfixes:
- Fixed that blueprints containing multiple charging rods did not paste their settings correctly. (Big thanks to thelordthygod for solving this meaty technical problem in their Blueprint Library mod.)
- Fixed that ghost charging rods couldn't have a polarity set.
- Fixed that ice platform and foundation tiles on Cerys collided with asteroids.
Balancing:
- Tweaked technology costs.
Optimizations:
- Charged particle optimizations.
Compatibility:
- Space Age Hard Mode: Kovarex is now unlocked by Moon Discovery Cerys and is no longer a prerequisite (since the Kovarex tech is locked behind Gleba+Fulgora).
Version: 4.8.0-4.8.2
Date: 2025-09-01
Changes:
- Slight tweak to charged particles after discussions in Discord. They are now deflected at 1/r^2 (from 1/r^1.5 in v4.0, previously 1/r^2.5 in v3). Compared to v4, this slightly reduces the complexity of long-range interactions and makes close-range collisions less abrupt. Also, the voltage of charging rods now increases with quality.
- Ghost charged particles now treat everything as fully charged.
- Ghost charged particle makers create ghosts in a [-0.5, 0.5]x[-0.5, 0.5] area rather than just at the tip.
- Water no longer spawns in the lithium brine area.
Version: 4.7.0-4.7.13
Date: 2025-08-30
Changes:

- Neutrons now behave differently in vacuum (their open-air behavior is unchanged).
- Crafting Neutron bombs no longer require processing units.
- Charged particles now move slower (but in the same paths and gameplay is unchanged).
- Radiation-proof inserters no longer switch states continuously if both the target and destination are valid targets.
- Renamed 'Explosives from ammonium nitrate' to 'Explosives by nitrate oxidation'.
- Improvements to map generation.
- Dry ice can no longer be paved over without melting it.
Bugfixes:
- Fixed that the U235 in nuclear scrap recycling was incorrect since 4.0.
- Fixed that launching hydrogen bombs from Cerys to space platforms would trigger the atmospheric explosion visual effect.
- Fixed that the new Cerys concrete tiles could not be selected by the deconstruction planner or pipette.
Balancing:
- Adjusted the Pu238 amounts in various recipes.
- Tweaks to technology costs.
Graphics:
- Graphical improvements to tile transitions, methane ice, and particle ghosts.
Sounds:
- Soundtrack adjustments.
Compatibility:
- Fixed a crash when the following three mods were present at once: K2SO, BZ Tin, Wooden Cerys Lunaponics.
Version: 4.6.0-4.6.4
Date: 2025-08-29
Changes:
- Crafting Overclock modules no longer requires superconductors.
- Added hydrogen bombs to the Cerys cargo drops whitelist (in case players accidentally launch it to a platform rather than to orbit).
Graphics:
- Frozen concrete tiles now have custom graphics on Cerys.
- Players in orbit around Cerys now see the flash from hydrogen nukes launched from the surface.
Balancing:
- Reduced the crafting time of Space science pack from methane ice (-50%), charging rods (-50%), and the reactor scaffold (-50%).

Bugfixes:
- Fixed that the rocket weight of Plutonium-238 and Plutonium-239 was 5x higher than intended (it now matches that of uranium rocks.)
Balancing:
- Reduced the rate of cooling of heat pipes and boilers on Cerys (-50%). This makes it easier to build large heat pipe setups.
- The reactor cooling rate now decreases with quality. These values are now shown in the entity tooltip.
- Nuclear scrap recycling: increased pipes (1.7% -> 2%) and heat pipes (0.5% -> 0.8%).
- Reduced the cost of cryoplant repair (-20%).
- Cryoplant wrecks have an additional module slot.
- Reduced solar panels obtained in ruins (-29%).
- Reduced the concrete obtaned by excavating the Fulgoran reactor (-20%).
- Adjusted the cost of various technologies.
Sounds:
- Added two music tracks.

- Reinstated the Overclock module by popular demand.
- Renamed the Metastable module to the Radioactive module.
- Reverted the v4.0.0 change that gave charging rods higher energy storage capacity. This is to reduce the awkwardness of setting up charging rods for testing.

Date: 2025-08-20
Changes:
- The Hydrogen bomb recipe no longer includes Plutonium-238.
- Radiation-proof inserters now disable themselves if receiving the red 'X' circuit signal.

Version: 4.0.0-4.0.6
Date: 2025-08-18
Info:
- 4.0 release. According to a long-time Cerys playtester, "In terms of grind, it is really a vast vast improvement." 4.0 also reworks the science tree, adds a Tier 4 prod module reward with a twist, adds a charged particle testing entity, and has the player blast a hole in the magnetosphere.
Features:
- New completion reward: Metastable module. This is a radioactive Tier 4 productivity module that decays to a Tier 2.5 equivalent, but can be recharged with Plutonium-239 in a centrifuge. The new Radiation-proof inserter is designed to insert it directly into machine module slots, and automatically flips itself when required.
- A new entity assists with plutonium farm planning by allowing players to simulate their effectiveness.
Changes:
- The Cerys tech tree is now less linear, giving players greater choice over which research to pursue next.
- Cerys technologies no longer require automation (red) or utility (yellow) science. Some instead require space science, which can now be crafted on Cerys using methane ice.
- Cerysian science has been renamed 'Reverse-engineered science' and is simplified to require holmium plates instead of superconductors.
- Charged particles now evaporate when they come to a stop.
- Charged particle deflection now occurs over longer distances.
- The cargo drops technology is now called 'Blast a hole in the magnetosphere' and requires the player to launch a hydrogen bomb into orbit.
- The final radiative towers technology now allows the player to mine the Fulgoran radiative towers on Cerys.
- Machine quality upgrades no longer require quality chips, instead simply requiring 5 repair parts.
- Nitrogen-rich mineral processing has been renamed 'Mineral leaching' and is simplified to no longer require water.
- The Overclock module has been removed from the Cerys tech tree as it wouldn't have been added if the Metastable module was in place. Already-crafted Overclock modules are retained.
Balancing:
- Repair costs of Fulgoran cryogenic plants reduced.
- Charging rods store +50% energy, but appear less frequently in ruins.
- The mixed-oxide fuel cell recipe no longer admits productivity modules. In order not to break existing space platforms, legacy saves that have completed Cerys unlock a secret technology granting the lost productivity bonus (Legendary T3 equivalent).
Graphics:
- New icons for repair recipes.
Sounds:
- Added a track to the custom soundtrack.
Compatibility:
- K2SO: The Gas power station now has a max ambient radiation condition.
Version: 3.8.3-3.8.4
Date: 2025-08-09

Sounds:
- Added a track to the Cerys soundtrack.
Version: 3.7.1
Date: 2025-07-28
Bugfixes:
- Fixed a bug introduced in v3.7.0 in which radiative towers were permanently fueled.
Compatibility:
- Adjusted the Cerys ambient radiation maximum condition to 300 (from 200). This has no effect on gameplay.
Version: 3.7.0
Date: 2025-07-27
Changes:
- The ambient rate of cooling of heat pipes on Cerys is now slower for each neighbouring heat pipe it is adjacent to. This change is balanced to leave the cooling rate of heat pipes with 2 neighbours unaffected.
Balancing:
- Buffed holmium plates obtained from nuclear scrap recycling to 1% (from 0.8%).

Changes:
- Added a recipe to upgrade personal mixed-oxide reactors into personal fusion reactors.
- Crafting mixed-oxide personal reactors now requires Pu239 in addition to Pu238 for flavor reasons.
- Fully charged high-quality charging rods are now able to store energy at lower voltages than their lower-quality counterparts (10% per level).

Balancing:
- Like the recipe 'Processing units from nitric acid', 'Speed module 3 from nitric acid' now requires fewer chips than the original recipe.
Version: 3.5.0
Date: 2025-06-30
Changes:
- Drive module replaced by a recipe for Speed module 3. This is because the Overclock module as published ought to require Speed module 3 to craft. Moreover this is a conceptual simplification.
- Overclock modules no longer require processing units to craft but now require Speed module 3 instead of Speed module 2.
- Recycling Speed module 3 on Cerys no longer produces tungsten carbide.
- Cryogenic plants can no longer be placed on Cerys.
Balancing:
- Reduced the energy consumption of the Fulgoran cryogenic plant (-16%).
- Increased the crafting time of certain Fulgoran cryogenics recipes: Cerysian science pack (2s -> 6s), processing units from nitric acid (1.8s -> 2s), methane ice dissociation (5.5s -> 6s).
- Increased the ammonia produced by nitrogen-rich mineral processing (+50%).
- Buffed the Overclock module by reducing the productivity effect (-5% -> -4%).
Bugfixes:

Compatibility:
- The errors reporting a missing Lunaponics mod now fire when the Factorio client boots.
Version: 3.4.0-3.4.6
Date: 2025-06-28
Changes:
- Due to Cerys' philosophy of avoiding disturbing vanilla, the level 4 productivity module (Yield module) has been removed due to its effect on the Space Age endgame.
- Removed the unlock of Productivity module 3 on Cerys (and the associated special handling of recycling it).
- Cerys now instead has two new modules with downsides: the Drive module (a Tier 2 prod module) and the Overclock module (a Tier 4 speed module). In the endgame, the Drive module generally becomes obsolete and the Overclock module plays a niche role.
Balancing:
- Increased the sulfuric acid in nitrogen-rich mineral processing back to 15 (from 10).
Version: 3.3.7-3.3.8
Date: 2025-06-27
Changes:

- Fixed a crash when using both Maraxsis and the 'Remove all cargo drop technologies' mod.
Version: 3.3.4
Date: 2025-06-27
Changes:
- Overclock module renamed to Yield module. This name fits better due to the reduced speed.
- Yield module technology requiring Maraxsis science packs is now an option, disabled by default.
Balancing:
- The Cerys recipe for Productivity module 3, as with the Yield module recipe, no longer accepts quality modules.
Graphics:
- Graphical tweak to the Yield module.
Version: 3.3.3
Date: 2025-06-27

Compatibility:
- K2SO: Adjusted Cerys for the fact that K2SO merged the Space Age and K2 lithium items two days ago.
Balancing:
- Overclock module buffed from 17% productivity to 18% productivity and speed debuff changed from -25% to -30%.
Version: 3.3.1
Date: 2025-06-26
Changes:
- Adjusted the Fulgoran Cryoplant Prod 3 recipe to require green chips instead of red.
- Productivity modules no longer recycle to biter eggs when recycled on Cerys (but still do outside to maintain vanilla compatibility).
Version: 3.3.0
Date: 2025-06-26
Features:
- One more planet reward, likely the final to be added: The Overclock module, a type of Tier 4 productivity module with strong productivity at a drawback of inhibiting quality by -100% (along with significantly reduced speed). Quality modules cannot be used when crafting it.
- An alternative recipe for Productivity module 3 is now available in the Fulgoran cryoplant.
Changes:
- Rearrangements to the tech tree.
Version: 3.2.3
Date: 2025-06-26
Changes:
- The initial scaffold used to repair the reactor will now transfer its quality to the resulting repaired reactor.
Version: 3.2.0-3.2.2
Date: 2025-06-26
Info:
- This update brings deeper compatibility with Krastorio 2 (via the Spaced Out mod). It includes a few breaking changes to existing K2SO bases on Cerys, namely recipe changes to utility tech cards, nitric acid, and certain recycling recipes.
Compatibility:
- K2SO: Merged the Cerys and K2 nitric acid fluids.
- K2SO: The Cerys recipe for Nitric acid is now performed in the Fulgoran cryogenic plant using ammonia and oxygen.
- K2SO: Utility tech cards now have a surface-specific tweaked recipe for Cerys. This means that reactor repair on Cerys is necessary.
- K2SO: The recipes for charging rods and the Fulgoran reactor scaffold now require steel beams instead of steel plates.
- K2SO: Rare metals are no longer provided in nuclear scrap recycling.

Since Factorio cannot handle migrating tiles that contain covering tiles which would now collide, old saves are migrated to have Cerys surrounded by the empty-space tile.
Version: 0.9.21
Date: 2025-01-18
Changes:
- Re-removed the limitation on requesting a maximum of 200 ice tiles to transition at once, since this will be unrelated to the reported bug. This fixes ice melting in an unusual order.
