No. He clearly won the game by killing himself, which should not be possible. This is not the first 'glitchy' thing to happen on the GG server in the past few weeks either. The other day, I was playing gg_sex_fix and was on nade. I had already thrown my nade and had an auto shotty and was trying to kill someone to get another nade. As I was shooting, a nade explosion went off (I assume I shot the nade perhaps? No idea what happened), the game registered that Colby <ibis.a> had killed HIMSELF with a nade and I was awarded the win.
Shot registration is really off too. It's hard to pin down though, because it sometimes seems to be spot on and other times it's as if you're shooting air when there's clearly a person right in front of you. Very strange.
Reboot and defrag! LOL
