⚛ Antimatter Chemistry Reforged

There is nothing in this world. You will build everything from atoms.

You spawn on an endless white plain. No ores. No trees. No water. No stone. Just four layers of white antimatter over bedrock, as far as the eye can see, and a starter chest with two machines.

The Dissolver breaks the ground under your feet into elements of the periodic table. The Combiner puts atoms back together into anything you need. An iron ingot costs 16 atoms of iron. Steel is 15 iron and one carbon. Every plank in your chest was once a handful of rock.

Then you find out the elements you need are not in the rock at all. So you split atoms in a fission reactor, fuse them in a fusion chamber, synthesize element 119 that does not exist in nature, and at the very end you build antimatter, dark matter and a 25-part Certificate that proves you mastered every major mod in the pack.

1,366 quests. 28 chapters. 118 elements, 175 compounds, 3,481 fusion recipes. One block to start with.

🧪 Why this pack is different

Real chemistry, not a reskin

Every element and compound has its formula, state of matter and color. Fission takes you down the periodic table, fusion takes you up. Dissolver chances are exactly what JEI shows. Rare metals are rare because they really are, and you will feel it when the table starts to run out.

"Chemistry only" hardcore

Every shortcut that skips the chemistry is gone:

• No ores in any dimension. Not in the Nether, not in the End, not in the Twilight Forest, not on the planets of Ad Astra.
• No raw resources in loot. Chests keep their unique treasures, but ingots, diamonds and ores are gone. Mobs do not drop metal either.
• No trading. Villagers and wandering traders never spawn. Piglins take your gold and give nothing back.
• No free energy. Solar panels, wind turbines, RTGs and passive heat generators are cut. Lava and water make only cobblestone.
• If something cannot be found in the world, it has a recipe. JEI will show you which one.

Machines you will not find anywhere else

The pack runs on Alchemistry Plus, our own fork of Alchemistry:

• Enricher: 16 blocks of antimatter and 250 mB of water become Trace Concentrate. An osmium ingot drops from 1,600 blocks of digging to 320.
• Spectrometer: right-click any block and its full composition, with chances, appears in chat.
• Cryo Chamber: a 5×5×5 multiblock with three Cryo Cores. YBCO superconductor cools in liquid nitrogen, NbTi cable in liquid helium.
• Synthetic Crude: real Fischer-Tropsch oil from carbon monoxide and hydrogen.
• Industrial and Cascade machines: 4 and 16 operations at once, for when one Dissolver is no longer enough.

Every mod leans on another

Nothing here is a side attraction. Every Draconic Evolution tier needs a part from another mod: AE2 processors, Create precision mechanisms, Mekanism circuits, Powah capacitors, Ars Nouveau gems. Fusion injectors need metals from three different planets. The particle accelerator's magnets are wound with cable from the Cryo Chamber. The final exam asks about everything.

An endgame that is actually an endgame

• Particle physics. Nuclear Science's accelerator smashes particles at near light speed for antimatter and dark matter. Every collision costs 400 MJ.
• Neutronium is pressed from antimatter cells, not collected from thin air. A full Infinity set takes around 16,000 of them.
• The Infinity Ingot needs dark matter, Powah nitro crystals, Ad Astra calorite and TFMG electric motors.
• Infinity gear is built on top of the best gear of other mods: MekaSuit, Chaos armor, Draconic chaotic tools and Industrial Foregoing's infinity drill, saw and trident.
• Radiation is off and reactors do not blow up your base. The challenge is the chemistry, not cleaning up craters.

🗺 The road ahead

Chapters open as you progress, and key machines are tied to seven progression stages, so nothing skips half the pack.

🚀 Things you will remember

• Building a Nether portal out of obsidian synthesized from atoms, because there is no lava on the plain.
• Flying to the Moon, Mars and Venus, and dissolving the planets themselves for desh, ostrum and calorite.
• Opening the portal to the Otherside with a Heart of the Deep crafted in a Combiner.
• Mob farming that starts with cursed earth brewed from arsenic and mercury.
• Watching a Cascade Dissolver chew through a mountain of antimatter 16 blocks at a time.
• The day the last element of the periodic table drops out of your fusion chamber.

⚙ Getting started

• Minecraft 1.20.1, Forge 47.4.10
• Give the game 8 GB of RAM (6 GB minimum)
• Create a world with the default world type: the antimatter plain turns on by itself, and the starter chest arrives the first time you join
• Works in singleplayer, LAN and on servers. Team up with FTB Teams, protect your base with FTB Chunks, and race your friends to the first antimatter.

❓ FAQ

Where do I get iron?

From the ground. Dissolve white antimatter: iron is the most common element in it.

There is no water. How do I start?

Your starter chest has a water bucket, and the first chapter shows how to make water endless.

An item fell out of my inventory and I cannot pick it up.

That item belongs to a later stage. The quest book tells you which chapter unlocks it.
