Its actually also the my most epic moment in gaming.
Me and three friends were playing 2 on 2 CoD4 on Backlot [http://forum.i3d.net/attachments/technische-hulp-cod4/14668d1205223319-cod-4-info-helpdesk-backlot.jpg]. The game was still new so no one was able to run or maneuver as fluidly as the "hardcore" crowd does now. Luckily we were at... lets call him Jon. We were at jons house, who's game room basically has 3 walls and a tv instead of 4 walls. So screen peeping means you have to completely un-focus from your screen and risk dying horribly, so privacy is pretty solid.
Anyway, Me and my partner, "DJ", started up looking for the other two Jon, and... Steve. The 4 of us basically wondered around for 10 minutes with no result (a LONG fucking time in FPS multiplayer match). 10 minutes of tense cat and mouse in dead silence. We were all pretty stressed looking for each other. Using everything we could think of, clearing corners and shit like that.
Finally I found an turret placement on the second floor of a destroyed building (top right, second from the top. With the jacked up roof.). It overlooks an main cause way. The moment I got on it I spotted both of em'. Walking my direction completely crouched. I immediately got off and ducked down and waited till they were closer.
They came to a small piece of cover where they were going to pop out simultaneously in case me or my teammate were waiting for them. I jumped on the turret, aimed it, and unloaded on the two of em' killing pretty much with the same initial burst. The tv was up pretty load too, the sweep made Jon drop his controller cause he was so surprised.
After that the game got rolling and they kicked our ass, but still.
It only got 2 kills, but its the proudest 2 kills I have ever gotten.
