Advanced Compounds & Alloys

Advanced Compounds & Alloys

AC&A is a very large mod mainly based around science. It is MOSTLY scientifically accurate, but of course not completely, some things are simplified for gameplay (though not massively) and some things I have not been able to find good sources.

AC&A

AC&A is a mod that adds primarily chemistry, but also a lot of other things.
Like cooking, QOL, bosses, dimensions, building blocks, etc..
It's made by me! (San/Tiktakalex/Snan), my friend InotPCW, and my 3d modeler Keluzafish.

COOL BUILDING BLOCKS!

AC&A adds a lot of new building blocks!
Though fair warning! I am not good at pixel art and anything visually pleasing is just luck.

INSANE CHEMISTRY!

AC&A adds tons of realistic chemistry (it is mostly accurate real life chemistry, but i will not claim it to be 100% (as that would be stupid) accurate, but mostly, again, mostly accurate, but theres a limit), from extracting simple materials to making supercomputers and beyond!

SILLY STUFF!

DINO NUGGIES!! (and other small things tahat you'll have to find yourself)

MAGIC!

AC&A also adds magic and alchemy! I mean, what did you think? I was gonna contain myself to one subject? Stupendous.

COOKING!

AC&A adds lots of food like fried eggs, goulasch, hotdogs, and other stuff too!

AWESOME MACHINES!

AC&A adds a lot of single (and multi) block machines, that serve all sorts of purposes, both QOL and progression in the mod!! THOUGH, i still need to add blueprints for some of the multiblocks.

{ABOUT REALISM}

So, i tried to make this as scientifically accurate as possible. I have researched real life reactions. But there are obviously limits, gameplay simplifications or misunderstandings that would keep it from being 100% accurate.

-> PEOPLE THAT WORKED ON THE MOD <-

San (Snan)

Main dev - Made like literally 99% of the mod.

Phil (InotPCW)

He helps sometimes, made a few textures (like shineberries) and is a pro painter! (Made some paintings) uhhh, and does stuff.. Marketing.

Keluzafish

Makes like 99% of our 3d models, with the honourable exeption of the dimensionator (san)
He also (for some reason) have no modrinth account.
