The best kill I've gotten was in a CS scrim. It's 5v5 competative play, which makes kills even harder. It was a 3v1 clutch on dust2, and I took out two guys with relative ease but time was running out. The guy ran down long, and with no choice but to chase him I did. He got into pit and I assumed he was behind the box. At 0:00 seconds, I jumped into the air and sprayed at the box as best I could with a silenced m4. I got a headshot and won the round.
Random? Yes. Could I do it again? No. Did it feel like I won the lottery? Yes. Yes it did.
