I was playing Big Team Snipers on Boneyard, in Reach, and I was on the back of a mongoose. So while I was riding I saw a enemy. Well since we weren't going to stop to kill him I knew I was only going to have one chance to kill him. Well when we drove by him, headshot with my sniper rifle on my first try. I felt like a boss. It's on my file share if none of you believe me.
