That being said the problem is very, very simple, (and would be easily expressed via video perfectly)
In a nutshell, I'm being killed practically instantly by any gun at any range in any armor mode roughly half the time when playing multiplayer on the 360. I've walked into a room while someone was fighting someone else with the k-volt, been clipped by a single shot from it in the foot, and fallen over dead. I've been shot through a tent wall at ~25m from a grendel single burst while sprinting with a slow-motion headshot from the *first* bullet of the burst (it went into the slow-motion the moment the trigger was pulled, by the looks of the cam).
These are the type of kill I would normally shrug off as "well, maybe 3 people saw me at once and my time was up." or "perhaps I ran on top of a grenade right as he fired" mishaps that can happen so frequently in high-population areas. But as I've continued to play (out of some deep sense of self-hatred, apparently), this has become consistently half or more of my deaths. I checked my connections, and it can happen on any amount of connection, the dreaded "is there even a colored bar there?" to the full greens I presume mean I'm hosting. Always the same result.
Some of the killcams have been funny to see...as I just tump over for no real reason....but now its getting really, really old. To the point where I'm considering returning the game.
Is this a common problem? I've found tons of posts about hit detection, latency, etc....but nothing with this specific issue. Any help would be greatly appreciated!
