Repair Tool Guide
Repair Tool searches are practical: players want to know where to scan, which route is safer first, and whether the tool unlock is worth a deeper wreck trip.
Quick answer: EA 1.2 unlocks the Repair Tool after two scans. Start at Chap base, then choose either the south wreck or northeast wreck for the second scan. We keep all three known route leads so the unused location can serve as a fallback.

Route and unlock plan
Chap base first, then either the south wreck or northeast wreck for scan two.
Step 1
Scan the easiest route first
Chap base is the cleanest first stop because it is a small base route rather than a deeper wreck interior.
Step 2
Choose one wreck for scan two
EA 1.2 only requires two scans, so use either the south wreck or northeast wreck after Chap base.
Step 3
Keep the third route as a fallback
Use the remaining wreck only if it fits another scan trip or the first option is awkward in your save.
Step 4
Craft only from current text
Fragment routes and recipe rows can drift separately, so read the live craft prompt before writing costs.

Player decisions
| Question | Status | Rule |
|---|---|---|
| First scan | Chap base route | Best first stop when you want less wreck-navigation risk. |
| Second scan option A | South wreck | Good after oxygen upgrades or stronger route discipline. |
| Second scan option B | Northeast wreck | High-value when you want a multi-scan trip; no third Repair Tool scan is required. |
| Main risk | Wreck exits | The danger is usually losing the exit line, not the fragment itself. |
