for this you will need two of your frends and they have to be 7 lvl minimum to unlock ranked you must be plat or higher to be able to get it.
If everything is checked you and your 2 friends can cue up for a ranked match, it will be best if they are broze so then they wont lose any points.
Your friends will have to leave the game and you will be able to cotrol them as bots just turn of running and firing and there you go, you will get all the kills and most importantly you will get all the damage
