Tech tree
The Graveyard Keeper 2 tech tree, grouped by the game's own categories. Each row lists the red/green/blue points the node costs, its prerequisites, and what it actually hands over — recipes, buildings, formulas. Nodes with nothing listed carry no unlock entries in the data; they exist to gate further research. Every node the game itself names is listed; the unlock-only nodes that carry no player-facing name are not.
