| Alembic Patch 1.1 | 2026-10-23 | Alembic 1.1 — Particles and LightHello! It's been an amazing first month and a half since launch, and it's been a lot of fun seeing the cool things that the community is building and discovering! Our first major milestone patch includes a number of bug fixes, requested features, an expansion of the existing particle system and the addition of light and optics!Have a read through the detailed additions below, and please join us in Discord!Patch 1.1 Power from heat and decay- Thermopile - a new machine that makes voltage from a temperature difference across its body. Hot on one face, cold on the other, and its terminals go live. Reverse the gra |
| Patch 1.03 | 2026-09-25 | 1. Sodium azide chain — BUILT - NH₄NO₃ above 250 °C → N₂O + steam - Na + NH₃ above 200 °C → NaNH₂ + H₂ — must be sealed, sodium ignites at 100 - 2 NaNH₂ + N₂O above 150 °C → NaN₃ + NaOH + NH₃ — balanced cell for cell, three in three out - Bonus: NaN₃ is binary with no anion, so it takes a decomposition threshold — heat it and it cracks to sodium and nitrogen. Airbags! 2. Actinide decay loop — FIXED - Not a decay-data bug: Ac→Th, Th→Ra and Pa→Ac are all real - The loop was neutron capture running the ladder backwards — Th+n→Pa, Ra+n→Ac, Ac+n→Th closed two rings, each lap depositing heat from nowhere - Root cause: the sim tracks protons only, s |
| September 18, 2026 Patch 1.02 | 2026-09-18 | September 18, 2026 Patch 1.02- Seeds now sink in water instead of growing and collapsing awkwardly- Update to translations and localization to improve formula renderingNewly Reachable:Calcium Carbide - Ca + C | Heat it without oxygen!Acetylene - CaC2 + H2O | Should also produce slaked limeEthylene/Propylene - Naphtha + Steam + HeatGlycerol - Propylene + O2 + Steam + Heat | Careful with your heat balance!Nitroglycerin - Glycerol + Nitric Acid | Low temps only!Nitroglycerin is unstable! Other shockwaves in the scene may cause it to detonate 👀Ammonia (better modelled) - N + H + HeatAmmonium Chloride - NH3 + HClAmmonium Carbonate - NH3 + CO2 + H |
| Friday, Sept 11, 2026 Patch 1.01 | 2026-09-11 | Hotfix: Cataclysm, pipes, and optionsCataclysm is more easily reachable.Pipe elbows are sealed. A bend drawn with a narrower diameter than the run before it leaked at the corner. The old outlet is now closed properly whatever the widths, and two-click corners get a full outer casing instead of an open notch.The codex shows what reactions make. Every discovered reaction lists its products, and a pair that makes different things in different conditions collects each outcome. Reactions you found before this update show nothing until you trigger them again — redo them and they fill in.Frame rate cap. New in Options: Off, 30, 60, 120, 144 or 240. |
| The Pre-launch Acid Update | 2026-09-06 | The Acid Pre-Launch UpdateNine acids with real relative strengths, bases that neutralise by quantity, and a pH axis that runs the whole way from fuming nitric to soda water. Gold now has something to be afraid of.AcidsEvery acid is ranked by its real pKa, so strength behaves like strength. Lower is stronger:HI(aq) − 10.0 — hydroiodicHBr(aq) − 9.0 — hydrobromicHCl(aq) − 6.0 — hydrochloricH₂SO₄ − 3.0 — sulfuricHNO₃ − 1.4 — nitricH₃PO₄ − 2.15 — phosphoricHF(aq) − 3.17 — hydrofluoricH₂CO₃ − 6.35 — carbonicH₂S(aq) − 7.00 — hydrosulfuricConcentration is a real axis. Acids dissolve the way salt does and spread by diffusion. Corrosion rate follows pr |
