I've noted this in the campaign as well, I take 3-4 shots at the A.I and it just won't die until a 5th shot.

In the campaign I've decided to set it at the lowest difficulty, then set the enemy A.I skill value to = 0.00 and they STILL just stand there, look at me for at least 1 second *this happens while I am prone as well.* then somehow just one shots me. This issue really just infuriates me greatly and it's just pushing me farther away from trying to enjoy the campaign entirely, this must be resolved soon!

I was playing campaign yesterday night, on the 14th mission of the first bit of the campaign. When I get to the part where we have to run north to Evac Stratis the A.I that spawn from the Kajman on the hill some how just flick around then just one shot me after barely looking at me for a second. I've tried toning down the difficulty AND setting the enemy A.I skill value to 0.00 and they still pull this stupid move off. THIS NEEDS TO BE FIXED ASAP.
