• Particle Accelerator Pixels are here!!! (1.0.58) - 29 September 2026

  This update finally adds particle accelerator pixels! They are currently craftable through the same category as the lasers, require super-heavy isotopes (so you have to do the manually isotope production to some degree first), and use power from the grid (currently 16 kJ per tick, to match the Particle Accelerator tool). There is an Alpha Particle Gun, Neutron Gun, and Proton Gun :)Other additions in this update:Heat Pumps now transfer the heat from within themselves as well as from behind them, making the best way to build them a solid row of Heat PumpsMonster Ring previously required Slime for purchase, so you still couldn't use it to access Slime/Ectoplasm in Creative Mode; this is now fixed (cost changed to Cellulase + Lipase + Nitric Acid)Allow static pixels in Select Material Window for Sensors again, to reallow machines that detect wheat, ice, and some other thingsAdded a Lava So…

• Hydrofluoric Acid & Plastic, Enthalpy Update, and More! (1.0.56) - 26 September 2026

  Pictured: the new Heat Pump pixels :)Hydrofluoric Acid Updates & PlasticHydrofluoric Acid now reacts with many more things, including Ceramic Walls! To contain Hydrofluoric Acid, you can now create plastic (PTFE - polytetrafluoroethylene) and build walls with it. Ethylene now is one of the things that evaporates from Naptha (product of separating oil), and is used to produce TFE (tetrafluoroethylene) and then PTFE.List of new things Hydrofluoric Acid reacts with: Alumina, Apatite, Corundum, Flint, Magnesium Oxide, Olivine, Quick Lime, Rust, Zinc, Zinc OxideEnthalpyExothermic/endothermic reactions are now more realistically simulated, using an Enthalpy value (in Joules) instead of a TemperatureChange value - this allows the temperature change from reactions to act properly with regard to Specific Heat of the material in the cell. The Guide Tab shows the delta-H (Enthalpy) of reactions th…

• Quality of Life Updates! (1.0.54) - 21 September 2026

  This update adds some quality-of-life improvements that players requested:QoL: Larger sim areas now allowed: up to 10x10 chunks - this makes it a lot easier to run large scale machines all at once and pull the camera zoom way out :)QoL: Buttons in the Select World Screen to sort the world list Alphabetically or by Last Played (the buttons appear when you have more than one world listed)QoL: "Show HUD Backing" setting in the visual settings page - allows turning the black background of the HUD offQoL: Having the Helmet on disables the Fire character's heat/burn aura, and the Snowman character's cold auraBUGFIX: the filter list now respects the SuppressInGuide flag, preventing some internal-use materials from appearing in itBUGFIX: unmarked the SuppressInGuide flag on Paints, so their reactions will appear in the guideBUGFIX: fixed Mass of Carbon so it should sink in Water nowSeptember 21…

• Wrench shape settings and more hotfixes! :) (1.0.53) - 19 September 2026

  The Wrench tool now has the same shape options as all the other tools. :) This is convenient if you want to have alternating filters allow different things through a filter row. With this, I think all the current tools are aligned in how they handle the shapes you can draw and their UX.Other things in this build:BUGFIX: Can now pick up, drop, build, and mine materials while simulation is paused, which makes it much easier to build and edit structures while everything is frozen :)BUGFIX: Added a fix for making sure material localized names are cached for the correct current locale when joining a new sessionBUGFIX: added materials that were missing: Beryl Crystal, Topaz Crystal, Emerald Crystal, Sapphire Crystal, Amethyst Crystal. Basically, the buildable forms of all the crystals that currently have crystal-growth reactions, so now it should be possible to grow all of these crystals in m…

• Monster Ring and other Hotfixes :) (1.0.52) - 15 September 2026

  This update adds some hotfixes:BUGFIX: Monster Ring wasn't functional before - now it works :) It adds to the max monster count and doubles the monster spawn rate. This also makes it possible to spawn monsters in Creative Mode to get ectoplasm or slime.BUGFIX: RNG (random number generation) fix for IsReactionValid, should make reaction rates more consistent regardless of positionBUGFIX: fixed issue where a single pixel of exploding material on its own would keep exploding and not be consumedQoL: pinned Upgrades now save & restoreBUGFIX: adjusted weight of loam, sulfur so they sink in waterBUGFIX: flour is now in the food ingredients categoryBUGFIX: added another call to refresh localized strings when entering a new session - this is to try and fix a bug where UI strings wouldn't change to the new locale when entering a sessionREACTIONS: Nickel Sulfate + Lye -> Nickel Hydroxide + Sodium…

• RNG and other fixes :) (1.0.51) - 12 September 2026

  This build adds a number of bugfixes. The biggest one is that random number generation (RNG) is revamped to prevent inconsistencies that were present before. RNG volumes are now generated in a way to give guarantees that they will visit the entire value range for any given position, and some other fixes with how the RNG functions were being called fix an issue where the call would only get a subset of the volume (which interfered with the guarantees).All this means that the cooling pixels generating noble gases should work equally at all world positions, and this should also fix the issue where at some positions pixels of burning materials wouldn't completely combust.Other things in this update:BUGFIX: fixed Wood Gasification (Pyrolysis) reaction to not leave an empty space that would result in autoignitionBUGFIX: improved the collision detection for Actors to prevent animals from falli…

• Fungus Update! :) (1.0.50) - 10 September 2026

  This update lets you grow fungus and obtain various useful materials from it! :)Fungus spores will now change into the static fungus pixels when they settle on a material that fungus is able to grow through. Here is the current list: Dirt, Loam, Limestone, Limestone Wall, Apatite, Olivine, Compacted Dirt, Wood, Wood Wall.The static fungus pixels grow hyphae (collectively: mycelium) into the material when they receive Water or Sugar Water (fungus consumes Sugar Water much more rapidly). Pulses of energy move through the mycelium, extending it, whenever the fungus consumes something.When the mycelium breaks through the bottom of something and encounters open air, continued growth causes it to form streamers, which will keep growing in response to the growth signals when the fungus consumes pixels.This all makes it possible to form fungus farms, or to grow the fungus that already exists in…

• UI Scaling added! (1.0.49) - 8 September 2026

  Just a quick update to add this as fast as possible: UI scaling is now finally in the game!The default keys for scaling the UI are comma and period (they are rebindable in settings)The UI scale is saved/restored in the device save data.Also: this patch includes a bunch of localization strings for newer materials that had them missingSome more content updates coming soon! :)Join the Community today!DiscordYouTubeand if you haven't already please leave me a Steam review, it really helps me a lot!-Triplejump

• Soda :) (1.0.47) - 7 September 2026

  This update adds Phosphoric Acid and some ways to create a variety of sodas and cola :)(making soda is going to be important for an upcoming Slime Ranching update) Apatite also now mines into 3 variants: Fluorapatite, Chlorapatite, and Hydroxylapatite, each of which can react with Sulfuric Acid to obtain Phosphoric Acid. The three types of mined apatite can also be blending with water to form Clay, so that pathway is preserved. Existing Apatite Gravel in your inventory will convert into Fluorapatite.Can make Phosphoric Acid from Apatite or Phosphorus PentoxideCan make Citric Acid and Berry Mash by blending BerriesCombining Phosphoric Acid, Citric Acid, or Sugar with carbonated Water creates SodaFurther adding Sugar to Phosphoric Soda creates ColaAdding Sugar to Citric Soda creates Tart SodaAdding Berry Mash to Tart Soda creates Berry SodaSome other things added in this update:QoL: Added…

• Lasers, Mirrors, and Prisms! (1.0.43) - 5 September 2026

  This update adds a bunch of things related to lasers!Emerald, Sapphire, Amethyst, and Diamond Laser pixels are now craftable!Mirror Pixels are craftable from Silver and Glass! They deflect lasers, and can be opened/closed using signals. Two Mirror Pixels on a 45 degree diagonal will deflect an incoming beam as if they are a 45 degree line.Prism Pixels are craftable from Glass and Lead Oxide! They refract lasers by 45 degrees, and the rotation key can flip them between Prism Left and Prism Right modes.The values related to weight on materials (Weight, Density) are now replaced with Mass, and have been somewhat rebalanced for consistencyMaterials have had the follow additional properties added: Specific Heat, IsReflective, and Laser AbsorptionBlender pixels reflect an incoming laser beam in a random direction every tickLoose pixel forms of Mirrors, Prisms, and Blenders also have the laser…

• Hotfixes (1.0.42) - 3 September 2026

  Here are a couple quick hotfixes while I'm working on some bigger updates:QoL: delay resaving the *.universe file when the player restores an element so it doesn't create a pause - this is what was causing the freezing for some people when completing an element in the ship progression, so I wanted to get this in right awayQoL: changed the way spawning is suppressed by built pixels so that an animal/monster shouldn't spawn within a chunk that has anything built in it; hopefully this will cause nearby spawns to be less annoyingBUGFIX: 'map' console command was not working - fixedBUGFIX: updated Chinese translations for synthetic elementsBUGFIX: made grass roots grow on both dirt and loamA bigger update with a lot of laser-related things in coming soon! :)Join the Community today!DiscordYouTubeand if you haven't already please leave me a Steam review, it really helps me a lot!-Triplejump

• Hotfixes and Andesitic Lava Chemistry (1.0.40) - 1 September 2026

  Today I did a bunch of bugfixes, and also made adjustments to lava!Andesitic Lava now cools into Sodium Aluminosilicate, and I added reactions for Sodium Aluminosilicate and its downstream products: Sodium Silicate, Sodium Aluminate, and Aluminum Hydroxide, to connect it into other parts of the reaction web. :)Bugfixes in this build:BUGFIX: Rocket and Nuke Counters were not disappearing and were rendering over each other - this is now fixedBUGFIX: Paint materials were not showing in the material guide tab (fixed incorrect ui suppression setting)BUGFIX: Select Material UI no longer displays static material types in the listBUGFIX: Tool and Material HUD slots were still showing their tooltips when HUD was hidden using F6 - this is now fixed, and it seems like none of the tooltips from the HUD will show now when it is hiddenBUGFIX: HUD indicators that have hotkeys displayed on them: the St…

• PvE Survival Crafting Fest Sale! - 31 August 2026

  Atomcraft is on sale for the week of the PvE Survival Crafting Fest!!!Here's an overview of Survival Mode for new players:SURVIVAL MODE OVERVIEWSurvival Mode adds a lot of additional challenges to the core building/exploration-oriented mode, for example:Slimes spawn on the surface and are more prevalent (more combat)You need to eat regularly, and can eat raw pixels without having to wait to assemble them into a food itemYou need to poop after digesting food (default key: Z, although it will happen automatically if you try to digest with a full bowels)Some foods are toxic and will damage you when they digest (but you can vomit out the contents of your stomach with the V key)The Jetpack has a limited duration, short at first, but it gets longer with some special Survival-Mode-only upgrades (which you can start to unlock by the third underground biome) - because of this, there is more of a…

• Added Background Paintbrush! (1.0.34) - 31 August 2026

  The first pass of background pixels is now in!Using the Paintbrush, you can paint on the background using specific materials:Rose Petal + Egg Yolk (Blender) = Red Paint Marigold Petal + Egg Yolk (Blender) = Orange Paint Sunflower Petal + Egg Yolk (Blender) = Yellow Paint Cut Grass + Egg Yolk (Blender) = Green Paint Cornflower Petal + Egg Yolk (Blender) = Blue Paint Violet Petal + Egg Yolk (Blender) = Violet Paint Wood + Egg Yolk (Blender) = Brown Paint Calcium Carbonate + Egg Yolk (Blender) = White Paint Carbon + Egg Yolk (Blender) = Black Paint(you can also paint using the Slime pixels)Left mouse button draws to the background and right mouse button erases (you don't get the materials back when erasing - they are all fully renewable). Background pixels do not interact with the simulation - they are more for art and to add aesthetics to builds without interfering with the machinery. The…

• Quality-of-Life Improvements! (1.0.32) - 27 August 2026

  A bunch of quality-of-life improvements in this build!1.0.32:Added "Show HUD" toggle on F6UPGRADE: Recharge Rate 4 added, to make Particle Accelerator beam easier to useAdded Credits ScreenMade the achievement for the best ending also trigger the “escaped the asteroid belt” endingMoved the Sim Loader pixel to the first category of craftable pixels; it feels like it's better not to hold it back. Also, added to the craftable tooltip that you can press Alt to see the Sim Loader pixel's affected area.QoL: When searching for a material in the Material Guide Tab, exact match appears firstQoL: ability to pin NPC super dealsQoL: ability to pin what the NPCs want to repair their shipsQoL: add tier number on the color swatch for the laser so you know which level is whichQoL: ability to swap between previous drill tiers using the lower-left HUD (similar to the laser)BUGFIX: make Jump move the play…

• Save System Hotfixes (1.0.31) - 25 August 2026

  This adds a few things, mostly related to the save system:put in better containment for when errors occur on planet segments in the loading and saving processesin situations where a planet segment didn't get saved properly, will load as empty instead of being filled with sandBUGFIX: fixed a bug where not all active chunks would necessarily get marked to be savedBUGFIX: made the "Save As..." button use the localization setting of the gameMISC: added more specific logging when load/save errors occur to help track down remaining corruption bugsREACTIONS: added the Carbonic Acid route to Sodium Carbonate :)This should reduce the effect of write errors / corruption when saving, as well as provide better logging to figure out why it happens next time it occurs. Please let me know in the Discord if you experience any loss of parts of the map - I am continuing to put in fixes for various potent…

• Updated Save System! - 23 August 2026

  We have big updates to the save system in this build!The new save system will save everything related to a particular world into a singular .universe file in the Worlds directory (currently about 120MB). It does atomic saves and maintains a list of 5 rolling backups, so it should be much easier to restore if something happens and should sync much more easily using Steam Cloud (also will help keep us from hitting the Steam Cloud 10K file limit with multiple worlds!)Save migration will happen automatically - the build will load the directory-style saves from earlier and just save to the new format when the next automatic save happens. It will then prioritize the .universe file save over the directory (ignoring the directory if there is a same-name .universe file). New players will never have the directory-style saves.ALSO: you can save your own backup or create a branch of an existing wor…

• Performance improvements, started adding videos to menus :) (1.0.29) - 22 August 2026

  With this update I have mostly made some improvements to memory allocations and performance that should help to reduce stuttering for players who have been experiencing it.But also, I found out how to play video clips in Godot and started adding video previews to the crafting menu! The first three categories are about done - over the next couple days I will keep filling these out until we have examples for everything! :)I am still working on the big save system update, so don't worry, that's coming soon.Join the Community today!DiscordYouTubeand if you haven't already please leave me a Steam review, it really helps me a lot!-Triplejump

• More Quick-Fixes (1.0.28) - 21 August 2026

  Just a couple quick things today:QoL: If something is already in your Material HUD Bar and you Middle-mouse-button it to select it, it'll just select the existing material slot instead of assigning a duplicateQoL: Walk-Through-Walls Boots only operate when in Jetpack Hover Mode or when using the Jetpack if in Impulse Mode - this makes bases and platforms much more easily compatible with the Walk-Through-Walls Boots in Survival Mode :)BUGFIX: fixed the issue where saved/restored blueprints and blueprints uploaded to the Steam Workshop didn't correctly save and restore filter settings - now filters will keep their correct settings!BUGFIX: fixed an issue with the power grid where the reset rate wasn't tied to sim rate, causing power loss at lower sim rates - now power generation / usage is balanced regardless of the sim tick rateBUGFIX: clear map texture when exiting to menu so you don't s…
