Fatigue (Fallout: New Vegas)

Fatigue is a derived statistic

Mechanics
Fatigue is similar to Hit Points - but instead of causing death upon its depletion, a non-player character gets knocked out and becomes unconscious. If their fatigue is reduced to zero or below, the fatigue value is immediately set to -30. Additional fatigue damage can still be applied to a knocked out non-player character, but it cannot lower the value below -30.

While being unconscious, a non-player character can neither move or react, but is still considered alive and can suffer damage to the point of death. Unlike in Fallout 3, "fatigued" or "knocked out" characters cannot be looted; any attempts to interact with them will fail with the message " is Unconscious".

The fatigue stat is determined by a base fatigue and modified by a character's Endurance and level, as shown by the formula below. The approximate average fatigue rating for humanoids is 250. Fatigue's base regeneration is 1 per second, meaning that a non player-character will naturally recover from a knockout in 30 seconds.


 * $$\text{Fatigue}=\text{Base Fatigue}+(\text{Endurance}\times20)+(\text{Level}\times10)$$
