From The Vault
Nerves of Steel is a perk added to Fallout 3 with the Broken Steel add-on.
It increases the regeneration rate of Action Points.
This perk may be less useful to those who have chosen the Grim Reaper's Sprint perk, since that perk restores all your Action Points if you kill an enemy in V.A.T.S., however, since some of the new enemies added in Broken Steel can take more than one round of V.A.T.S. to kill, especially to players playing on harder difficulties or players with few Action Points, this perk may be considered useful by some.
It has been reported that the perk is non-functional on both the PC and Xbox 360 with the version 1.5 patch issued with Broken Steel, however this is inaccurate. While the perk does function, the increase in action point regeneration rate is extremely low (amounting to 1 additional AP per 10 seconds).
PC users can alter regeneration bonus associated with this perk by using the G.E.C.K. to edit the script DLC03APRegenScript. For users who do not know how to do so, a simple plugin can be found here.
