Find The Needle tech tree guide

What the tree covers

The tech tree includes over 300 upgrades that unlock new machines, improve production speed, increase efficiency, expand the factory and open new ways to process hay (full-game store page).

How to spend early points

1. Unlock the next named machine you need for a working sell or scan line (machines index)
2. Buy speed / efficiency nodes after the line already runs
3. Save factory size expansions for when belts and power are stable (conveyors and power)
4. Open new processing toward the products in production stages

Keep a money belt alive while you experiment — see sell hay and money.

Demo and Early Access

Practice the tree in the Demo. Early Access still targets all 24 needles across five stages (Early Access plan). Large unlocked yards are CPU heavy; check system requirements before a Mountain push.
