"One in a million" doesn't even come close to describing just how unlikely this kill is in Call of Duty: Black Ops.
Many, many people are playing Call of Duty: Black Ops every day via PC, PSN, and Xbox Live. With literally millions of man-hours being played every day since the game's launch, it's to be expected that we've seen some crazy kills, like first blood grenades to the nuts.
None of them compare to this.
I'm not going to spoil just what happens, but this is such a bizarre chain of sequential events that nobody could have planned out - like a Rube Goldberg machine of death - that I can't imagine something like it ever happening again.
It's enough to make one wonder, though - who gets the kill credit?
