Having been shot at and missed I can only say that my vision did not blur. Instead things became crystal clear with minute detail noted.
First firefight in Afghanistan went like this:
1. <As RPGs explode around truck> "Is this really happening?"
2. Senses become fine tuned, training creeps back in, you begin to operate like a machine
3. Legs began shaking uncontrollably...first thought is fear...then you realise that it is Adrenaline
4. Begin shooting those bad guys like there is no tomorrow!
Only time my vision became blurry was right after RPG exploded like 20 meters away sending me hurtling through the air and into the side of my Humvee...then was like holy watermelon that was cool...lol.
Sounds like something you would get with a PW on Xbox 360 or somethin
