or how about one that is kind of like oddball in halo, except in this one you carry a dragonball.
Whoever is carrying the dragon ball has to run from everybody, and when he dies he drops the ball. Then everyone has to run after the ball and pick it up. Whoever has the most time carrying the dragonball after like 5 to 10 min wins.
The dragonball will be pretty noticable on the radar too.
