Action Points

Action Points (or AP) is a game mechanic governing the number of things a player can do during one combat turn (in Fallout and Fallout 2) or in the V.A.T.S. mode (in Fallout 3 and Fallout: New Vegas).

Fallout, Fallout 2 and Fallout Tactics
Action Points are spent firing a weapon, reloading a weapon, fetching equipment from one's backpack or moving to a new battlefield hex.


 * $$\text{Initial level}=5+\left\lceil\frac{\text{Agility}}{2}\right\rceil$$

Example: A starting Endurance of 5.


 * $$5+\left\lceil\frac{5}{2}\right\rceil=8~\text{Action points}$$

Notes:
 * The Action Boy perk adds 1 AP per rank.
 * The Bonus Move perk adds 2 special AP per rank that can only be used for movement.
 * Notes: In Fallout and Fallout 2, the counter only shows up to 10 APs but internally it keeps track of any extras. In Fallout Tactics all APs show properly.

Fallout 3
Action points are used in V.A.T.S. to aim and fire at specific body parts.


 * $$\text{Initial level}=65+(2\times\text{Agility})$$

Example: A starting Agility of 5.


 * $$65+(2\times5)=75~\text{Action points}$$

Notes:
 * Every weapon has a certain AP cost for each shot queued. For the AP cost for each weapon, see the weapons page.
 * Maximum initial base is capped at 85 AP.
 * Maximum cap can be extended to 148 AP by utilizing specialized perks and equipment.
 * Maximum cap can be extended further temporarily by consuming specific food items
 * Total maximum with all temporary and permanent modifiers added is 268 AP
 * Unlike in the turn-based games, action points in Fallout 3 and Fallout: New Vegas are not accumulated at the end of a turn. Instead, action points are regenerated over time.
 * the Level 20 perk, Grim Reaper's Sprint restores all Action Points upon exiting V.A.T.S. if the player managed to score a kill during V.A.T.S.

Fallout New Vegas
Action Points in Fallout New Vegas function mechanically identical to Fallout 3, however the agility bonus is now times 3 instead of 2.


 * $$\text{Initial level}=65+(3\times\text{Agility})$$

Example: A starting Agility of 5.


 * $$65+(3\times5)=80~\text{Action points}$$

Notes:
 * Maximum initial base is capped at 95 AP.
 * Maximum cap can be extended to AP by utilizing specialized perks and equipment.
