From raw ore all the way to antimatter, this is every resource, ingredient and component your factory will ever touch: 99 items across eight tiers, pulled straight from the game's own files. Click any card to see its full spec plus every recipe that produces it or uses it as an input.
Items per tier, counted from the game's own files. The thickest ring is whichever tier has the most items, and choosing one filters the grid below.
Every item slots into more than one recipe, and these are a few chains that show how the game builds depth out of simple inputs.
Items, buildings and recipes all connect to each other, and in the game you can press K on almost anything to see where it comes from and what it goes into.
