Ok so yeah Been playing CoD4 since Nov... and yes I am still not that great, However I did pull something off that I thought I'd never be able to do... I'm half way through my 1st prestige mode so I knew the kill more than one person with a single bullet was a challenge to get that I didn't get the first time thru...
I was on the Missle launch board And I had the .50 Calibre Sniper Rifle laid down behind the crashed helicopter, and noticed that our A flag was being taken. I lined up the shot to the flag and there were four guys huddled up against the tank
I took the shot and noticed that I got a +40 and I looked again and I HAD KKILLED 4 FREAKING GUYS with 1 SHOT! Needless to say I got teh challenge bonus too!
I know it will never happen again and I'm sure others do it a lot but hey I suck!
But OMG!
