NINJA HUNTER

Ninja Hunter is 1 vs all (with rotations)

The object of the game is to score as many points as possible.

Ways to score are as follows:
Hunter kills ninja = 1 point
ninja kills hunter = 5 points

Everyone playing will have a chance to be a hunter and everyone will have a chance to be a ninja.
Each hunter has unlimited amount of lives but has only 5 minutes to kill the ninjas.
After everyone has been a hunter the game will end and scores will be counted.
Obviously the one with the most points wins.

Weapons:
Hunters will have guns
Ninjas will only have swords

Additional rules:
ninjas will have 30 seconds to hide from the hunter (so start running)
THE ENTIRE FIELD IS IN PLAY!!!

Round length should be: 5 minutes, or until the hunter dies. (Whichever occurs first.)

So, the hunter has one life. Everyone has one life per round. The hunter thus has to decide whether or not to take certain risks within the 5 minute time limit. The hunter should also ideally have a handgun as his/her only weapon, or any gun on semi-auto if there's no handgun. This is not a chill game.

The game could also be flavored as a zombie game if the situation demands it (Halloween club-event?).
