Chapter intro
Quick survival answer
Quick answer
Full-run rule
Do not treat Day 100 as one long rush. Treat it as a chain of checkpoints.
Long runs fail when players skip boring safety steps that make later danger survivable.
Guide
What to do first
Do these before chasing rare drops, region mysteries or long routes.
Track badge milestones such as Day 1, Day 5/10 and Day 100 as progression anchors.
Build raft safety before region hunting.
Use public full walkthrough videos as comparison leads, not copied scripts.
Save boss/region content for when health, weapons, healing and retreat options are ready.
