System-by-system comparison

SystemKey updateCurrent consequence
StealthUpdate 12Lighting and gradual detection matter; crouched archery remains possible.
PerksUpdates 13–15Clearer menus lead into complete skill ladders and a much larger roster.
AlchemyUpdates 14–16Vendor cleanup, harvesting flow and ingredient filters reduce inventory friction.
Co-opUpdates 13–16Host settings, guest character saves and broader sync fixes define the current model.
CompanionsUpdate 16Permadeath is optional and off by default; markers and persistence improved.

What older guides commonly miss

  • They may assume detection is binary or that bow aiming breaks crouch.
  • They may reference the pre-overhaul perk menu or retired perk names.
  • They may treat guest growth as disposable or companion death as mandatory.
