Moving between the two mountain maps
The mountain is two separate maps, 15:35 and 15:27, joined by teleport points. Going up needs the mission 合闸. Coming back down never does.
| Step | Where | Requirement |
|---|---|---|
| Foothills to Plateau | From the Foothills point in 15:35 to the Plateau point in 15:27 | The mission 合闸 must be complete. Until then the point reads "Inactive". |
| Plateau to Foothills | From the Plateau point in 15:27 back to the Foothills point in 15:35 | None. |
| Plateau to Summit and back | Inside 15:27, between the second Plateau point and the Summit point | None. |
Neither mountain map has a countdown.
The teleport creates a newly generated copy of the other map, so loot and enemies are fresh. Your insurance is kept and your recent-evacuation level does not change. Dying still ends the run as a failed run, and Death, overtime and gear insurance explains what that costs.
