NotesEdit

  • Other bonuses that stack with this perk in helping avoid detection are:
  • Rank 4 seems to completely eliminate the effect of footsteps on detection odds. If it is active then muffle armor mods are unnecessary and sneaking in power armor becomes much easier.
  • Rank 5 bestows an effect similar to that of a Stealth Boy or Chameleon armor effect when entering sneak mode, rendering the player, any equipped weaponry, and the Pip-Boy invisible for approximately one second. Note that this can interfere with aiming using non-scoped weaponry, or seeing the Pip-Boy display properly if brought up during that period of time. Unlike Chameleon armor, the player need not remain still for this effect to work.
  • The trap avoiding bonuses from ranks 2 and 3 of this perk also work when not sneaking.
  • All companions have the effects of 4 ranks of Sneak except Curie who is missing all ranks of Sneak in both forms (robot and synth). Dogmeat has a unique rank 5.
  • Sneak works very well with Ninja and other perks that increase the sneak attack bonus multiplier.

Behind the scenesEdit

  • The workings of sneaking in general and the associated perk/skill underwent a steady evolution with each new Bethesda RPG. One difference is how the AI reacts to an undetected opponent. In Fallout 3, everyone knew instantly where the player character was as soon as the fight started. In Skyrim, opponents would search for the player character, but be stupid about it and simply run to the location that they saw or heard something. In Fallout 4, opponents take evasive maneuvers, run in unpredictable ways, jump from cover to cover and try to take a detour in order to flank the player character.
