Biome pages need confidence labels

Early Access biome coverage should avoid turning predictions into facts. The useful format is a route card: depth band, oxygen pressure, resource value, predator risk, base value and source confidence. That lets a player decide whether to dive now, come back with better equipment or wait for a verified guide update.

What a good biome page should include

Each biome page should include what to bring, what to scan, when to turn back and how likely the route is to change. Players do not need vague atmosphere. They need a compact prep checklist and enough context to avoid wasting oxygen.

  • Depth band and oxygen pressure.
  • Core materials and missing-fragment likelihood.
  • Predator or cave risk without story spoilers.
  • Base suitability: power, safety, expansion room and route access.
