Home / Reference / Research Tech Tree reference Research Tech Tree Solarpunk research tech tree: all research unlocks arranged by tier with their costs and what each one unlocks (research and recipes), decoded from the game files.
This is the full research progression decoded from the game. Tiers are computed from the unlock graph: Tier 0 is available at the start, and each later tier is gated behind the research above it. Each row shows the cost to research and exactly what it unlocks.
The tech tree has 90 research nodes across 9 tiers, with 210 unlock links.
