Since the season will be starting in Iowa any day now, I've been attempting to come up with new game types in water warfare. I am quite terrible at it, so I ripped off of Halo.
As any Halo player should know, the object of Headhunter is to have the most skulls by the end of the match. Whenever you kill a player, a skull drops from their dead body and you can pick it up. You than take the skull back to a randomized drop off point, and the skull turns into points for you.
Here's the water warfare version, my rough draft for you guys to improve upon. At the start of the match, all player will be given a number of objects to put in their right pocket, their "lives" pocket. Spread out and start the match, which will last 5-15 minutes by the way. Whenever a player gets a kill, the "dead" player will give him one of his "lives" to place in his left pocket, the skulls pocket. The dead player must also hand over all of his skulls that he has not turned in at the drop off point that are in his left pocket. The drop off point is where players can drop off their skulls, where they will become points. Skulls that have become points stay that way the whole match. Whoever has the most points at the end of the match wins. Ta-da!
