Perception

Perception is one of the 7 Primary Statistics in the SPECIAL system. It represents the ability to see, hear, taste, and notice unusual things.

Fallout, Fallout 2, Fallout Tactics
Modifies: Sequence, ranged combat distance modifiers and the First Aid, Doctor, Lockpick, Traps and Pilot skills. A player character with higher Perception may notice things that allow them to open up new dialogue options on occasion. It also determines how far away your character starts from hostile critters in random encounters.

A high Perception is important for a sharpshooter.

In Fallout 2, Perception 7 or above is required for the Chosen One to notice the plug-in slot for the Pipboy on the Vault City computer; plugging it in and choosing the risky sounding Reformat option adds the Vault City Travel Log to the Pipboy. Noticing this slot makes it possible to obtain the Vault City Designer Notes after finishing the game; obtaining the Travel Log is not required for this purpose.

Perception is required for many perks, notably PE 6 for Sniper.

Fallout 3

 * Modifies Explosives, Lockpick and Energy Weapons skills

Perception also determines when red compass markings appear (which indicate threats). Be aware that a high Perception with a low view distance may be disadvantageous, as you will "sense" your enemies but not know where they are.

There are a few places in Fallout 3 where having a higher Perception will trigger the ability to notice certain things upon entering a room or building. Occasionally this can lead to useful discoveries.

Ways to increase Perception

 * The Perception Bobblehead can be found in the Museum of Dave at the Republic of Dave, located on the north east of the map.
 * The perk Ant Sight can be obtained from completing the quest Those!, which permanently increases perception by 1.
 * The Intense Training perk will allow you to increase your Perception (or any other S.P.E.C.I.A.L. stat) once for each time that you take it.
 * The Night Person Perk increases your Perception and Intelligence when the sun is down
 * Wearing certain pieces of armor such as Maple's Garb, Vance's Longcoat Outfit, and various pieces of headwear will increase your Perception by 1. The player is given a Pre-War Baseball Cap (+1 Perception) on his/her tenth birthday in the vault, for example.
 * Mentats can be used to temporarily increase Perception by 5.
