Karkinos dodgeball. 6 crabs, 3 per team. 10-15 aggressive ravagers from a 3rd tribe in the middle. The goal is to throw ravagers at the enemy crabs to kill them. You lose when all your crabs die. No smashing, shooting, jumping or tomfoolery. Just throwing ravagers.
If your friend is pissing you off, chuck them into orbit or even better, chuck them onto the surface of abberation. They will never piss you off again, maybe because they will never go on the same server as you again
