*I know this may have been known before, but if it was, I didn't know about it. I thought of this myself, but I may have not been the first.

You need 6 people, each with a guest.
Each round 1 person from each team goes and kills the other team (5 players, because 1 left to kill your team) then once your done, the guy with the bomb plants, and the defuser kills him and defuses.
You change off guys each round. The host, and 1 other lucky person go 3 times. (in overtime)

You should use a frag grenade, a quick kill smg (AK74u), and lightweight and marathon. Throw the frag first, and finish off any survivors with the AKu.
