Wiki/Tech tree

Workbench tech tree

The real tree, straight from the game files. Start at the workbench at the top and follow a branch down — you research each item before the one under it. Click any item for its scrap cost and what the whole path to it costs. A dashed sky line means that item needs a second prerequisite from another branch.

Workbench Level 1
3,180scrap for all 134
Bench costs 500 Wood, 100 Metal Fragments.
Workbench Level 2
6,075scrap for all 141
Bench costs 500 Metal Fragments, 20 High Quality Metal, 5 Basic Blueprint Fragment.
Workbench Level 3
2,235scrap for all 32
Bench costs 1,000 Metal Fragments, 100 High Quality Metal, 5 Advanced Blueprint Fragment.

Clearing all three trees is 11,490 scrap across 307 items. Every scrap figure here is the game's own per-item research cost, tiered 15 / 30 / 60 / 120 by how rare the item is.

No prerequisite

Unlockable the moment you have a Workbench Level 1 — these sit off the tree, nothing to research first.

Skipping the tree: the Prototype upgrade

Prototype Workbench Upgrade

Fit the Prototype Workbench Upgrade to a bench and the paths above stop mattering: it unlocks any tech tree item whatever your progression, so you can take the AK without buying the branch that leads to it. You pay for it twice over. The unlock costs double, and one in four attempts fails and still eats the resources.

You cannot craft it. It drops from the Military Crate at 1.7%, and it fits a Workbench Level 2 or better. At double cost a 120-scrap item runs 240, and the one-in-four failure rate pushes the average nearer 320 — worth it to jump a long branch for one item, a bad deal for anything you were going to unlock on the way anyway.
