Hallo fellow wastelanders!

I have been after this all around for a week now, tryed GECK myself and posted,asked around and alike in the Nexus forums so I ended up here looking for hope!

What I am after is, if you could please help, a mod where I can use the fatigue system! There is a mod in FO NV which uses fatigue and allows the player to knock out all enemies aside Robots, and even loot them while they are knocked out!

Now all I want is something alike in FO 3, And I know the fatigue system does exist! I tryed GECK but I am helpless when it comes to what to do!

Could anyone land a hand?
