i've walked up behind ppl (with new patch and old) and started knifing him and nothing.  this has happened more than once.  and tonite someone was leaning and i was shooting his a$$ with shotgun and nothing again.  i know, up close with shotgun, c'mon buddy, yeah, seriously, after he straightened up he died.  i never would had beleaved the shotgun thing, but now i do.  anyway, is this being looked into or no?  oh, and i would still like to add it would be nice if leaning was halfed when looking around rails or window....plz?  thx.

Ive had this problem a couple of time at first i thought it was a problem with the sniper rifle cause that is what i normally use. But then it happened when i was using the shoitgun crepped right up behind someone. who was leaning round some crates. Hit him three times with the but of the shotty but it didnt hit so i fired twice once as he was facing away. When i heard the shot turned around and took the second  in the face. Hit the floor like an anvil.

really? r u aiming at the head or the body at the time? can u still blungeon him?

I dunno, its a bit strange I've gotta say. Sometimes I can put a few bullets into the head someone who's leaning around a corner, and there's only a couple of hairs poking out, then like you, I go to get an easy kill in the back and nothing. Shoot again. Nothing.... Really annoying when you see them step to the side and there are bullet marks on the wall behind their head...

I can confirm this exists.

I butted a guy with the shotty three times from behind and nothing. He was leaning around a crate. He turned and we began hopping and shooting, and I killed him.

A weird problem.

yep same story here. There was a guy leaning around the corner in the lower tunnel in Kam2. The tunnel that leads to/from the base. Well a guy was leaning around the corner so I pulled out my knife and i couldn't kill him. I slashed at every angle, up and down his body for about 5 full seconds. Then i switched to either a shotty or rifle (i don't remember) and was able to kill him. But the knife was not doing a thing. Really really odd.

i've had this proble, before its really weird

just with the knife though

ditto here, only with knife
