Rust Blueprint Fragments
Blueprint fragments are a crafting ingredient for Workbench Level 2 and Level 3. The game files hold no recipe that makes them, so they have to be looted, and where they drop decides how fast a wipe moves.
Basic Blueprint Fragment
Used to craft Workbench Level 2, which takes 500 Metal Fragments, 20 High Quality Metal and 5 Basic Blueprint Fragments.
| Where it drops | Chance | Amount | Source |
|---|---|---|---|
| Supply Drop (Airdrop) | Guaranteed | ×2 | Game files, build 2634.289.1 |
| Metal Detector Finds | 14% | ×1 | Transcribed, not datamined |
| Military Crate | 10% | ×1 | Game files, build 2634.289.1 |
Advanced Blueprint Fragment
Used to craft Workbench Level 3, which takes 1,000 Metal Fragments, 100 High Quality Metal and 5 Advanced Blueprint Fragments.
| Where it drops | Chance | Amount | Source |
|---|---|---|---|
| Locked Crate | Guaranteed | ×2 | Game files, build 2634.289.1 |
| Elite Crate | 10% | ×1 | Game files, build 2634.289.1 |
What This Page Doesn't Claim
The chances above are per container. Rows marked “Game files” are computed from the loot tables in our dump of that build; the one marked transcribed is not, and is labelled so. Keycard puzzle rooms also hold fragments, but those are placed in the monument rather than rolled from a loot table, so our dump has no count for them and we don't print one. The same goes for trading basic fragments up to advanced: no crafting recipe for it exists in the recipe dump, so it isn't listed here as one.
