Hi guys! Hope this helps!

1. Start up this capture with a friend
2. Copy settings that I did
3.Return all the cases but 1 which is 7 like I did in the vid (you can only hold one at a time)
4.Kill all the people till you stop gaining rp, then return the last case
5. Switch off with your friend about who wins the round
6. After you finish go to freemode and collec the rp
7. Rinse and repeat
If you have questions, let me know in the comments sections below.
