— Fallout In-game description

Perception is one of the seven Primary Statistics in the SPECIAL system.

Fallout[edit | edit source]

Perception determines Sequence, ranged combat distance modifiers and the starting level of First Aid, Doctor, Lockpick, and Traps. It may also open new dialogue options and the player character placement in random encounters.

Fallout 3[edit | edit source]

Perception determines the initial level of Explosives, Lockpick and Energy Weapons. It also determines the detection radius, i.e. how close you need to be to a hostile creature or character for them to show up on the compass.

Perception can also provide additional dialog options with some NPCs, such as Moira Brown, Mel and Machete.

The benefit of the Survival Expert perk is affected by what you say to Moira Brown after each portion of The Wasteland Survival Guide quest. Having a perception of 7 yields relevant "smart" dialog options at the end of the Contract Radiation Sickness and Traversing a Mine Field objectives.

Fallout: New Vegas[edit | edit source]

Perception determines the initial level of Explosives, Lockpick and Energy Weapons. It also determines the detection radius, i.e. how close you need to be to a hostile creature or character for them to show up on the compass.

Notes[edit | edit source]

  • Perception does not increase V.A.T.S or regular accuracy at all, has been tested thoroughly and has been proven to be false.
  • If the player has a Perception of 8 while having no stats at 1 or a Luck of 10/1, Doc Mitchell will say "Nothing gets by you, huh? Coulda used you when I lost my keys last month."
  • If the player has a Perception of 1, Doc Mitchell will say "Now I ain't no optometrist, but maybe we should fit you for some glasses while you're here."
  • There are a lot of perception and Intelligence checks of 7+ in the Dead Money DLC
  • You can max out Perception starting with only 6 points in it, Four Eyes trait + Lucky Shades + Hat + Implant (6 - 1 + 3 + 1 + 1 =10).

Perception is your sense of environmental awareness and affects the hit chance in V.A.T.S.

Fallout 4 loading screen hints

With the absence of skills, Perception now directly affects accuracy in V.A.T.S., as well as base pickpocketing and lockpicking skills. Enemies no longer appear on the player's compass unless they're aware of their presence ([CAUTION] alert while in Stealth) or actively trying to attack the player ([DANGER] in Stealth). Friendly NPCs never appear on the player's compass.

Fallout Shelter[edit | edit source]

Lionheart[edit | edit source]

This is the ability to perceive the environment and notice things that others might miss. It is a combination of the individual’s senses, including touch, sight, taste, smell and hearing. This attribute factors strongly into a character’s ability to notice unusual things about the environment. Magic Wielders use this ability to understand their spirit, so Mana is partially determined by this attribute.[1]
