Now you will know really when should walk and run.
Add new effect to simulate your fatigue.
have too a new sound for wind (when you it is in high velocity, you hear that wind)
i recommend you to use my Variations of Sounds for Sprint Breath - Moddb.com - to better sensation of tired beyond this effect.
Updaded: fix breath inside of closed vehicles (tank, chopper, etc...)
Good Fatigue XD
