How to get scores like this

Keep your distance, if your ever in a domination, headquarters, demolition, be a defender at a distance and always watch your back. If you decide to play a deathmatch then stay behind your team so you will be the last one to do most of the time and kill from a distance. Theres nothing else to really say, i cant promise you a score like this because i usually don't do this good every match but it does happen enough. (my death was a suicide because i wanted my killstreaks back) The only i can really make you better is play against you.
