When you go in a match press back ,who ever has the best connection is the host so the person who isn't the host get 9 headshots.

Then back out then re join fast then get another 9 headshots, then do the same.

This is a lot quicker than normal. I did it and I got 93 headshots in 10 minutes on shipment.

When you get the hang of it it's amazing. Send me a message if you need help.
