Action_Points Events in TLA Mk2 occur in real time. As a result, every character has an action points (AP) score that is spent on attacks, using skills or items, and other actions. AP is regenerated only if the character is standing still and doing nothing. Every character will restore it's maximum AP score in 7 seconds, regardless of how much AP he has spent. For example:
If the maximum AP of the character is 7, he will regenerate 1 AP per second. if the maximum AP of the character is 10, he will regenerate 1.42 AP per second, or roughly 3 AP every 2 seconds.
Starting Action Points are equal to: 5 + (AG / 2) , rounded down.
The Action Boy perk can increase your AP total permanently, and the Adrenaline Rush perk and certain armor can increase it temporarily.
