Can someone level up your call of duty account?

Answer 1

Ya, Duh! You! Ill give you a hint, go to the Multiplayer lobby, get a total of 4 people, (you count as one) then press Find match, go to Barebones, then when you start searching press X and go to Free For All Barebones, then take someone to a safe place, one pops their tac, then the one who didint pop it kill the person who did, then when they respawn, let them pop their tac, then kill them again, keep doing this until you have 29 kills then the one who got killed 29 times starts to kill you until he/she has 29 kills, then end the game and start over, but wait for the other 2 to get 29 kills before you restart, keep doing that over and over, it will boost your gun and you, i did this boosting thing and i got to rank 40 in like 36 hours (a day and a half) .
