Quick Answer

Do caves in item-driven trips. Start with navigation tools, then collect survival and traversal items, then push story-gated routes. The exact cave number matters less than entering with supplies, knowing the target, and leaving safely.

Route priorities

1Map and compassStops cave routes from turning into blind panic
2Modern axe and better suppliesMakes building, defense, and combat more reliable
3RebreatherUnlocks underwater sections and later story routes
4Climbing axeOpens vertical cave routes and safer traversal
5KeycardRequired for major story progression
6Chainsaw / modern bow / optional gearSpeeds resource and combat routes when you are ready

Before every cave

  • Bring food, meds, armor, light, backup fire, and enough cloth.
  • Mark the entrance outside so you can return.
  • Decide the item goal before entering.
  • Do not overstay after collecting the target item.
  • Save at camp before a risky cave push.

Common mistakes

  • Entering the first cave you see and hoping it contains what you need.
  • Getting the item, then exploring deeper while low on light and meds.
  • Ignoring surface patrols on the way back to base.
  • Trying the ending route before rebreather, keycard, and supplies are ready.
