Mitsuko seemed to use it well

Kiriyama chopped that guy's head off and put a grenade n his mouth! Best weapon!

With a GPS, you can find people that just died, stay away from everyone else and grab their weapon.

a gun of course

At least to me, because I wouldn't want to kill anybody. You could defend yourself without having to take a life.

A gun of course.It would be a waist of energy havein to go up to people and strickin them with what ever other weapon.With a gun you could aim and shoot from really far away.You don't even need the effort to walk a few meters up to them.Just shoot and aim from where ever your standing and job done! Although Mitsuko did a great job with the axe though :D lol

You don't have to get close so it's not dangerous to yourself.
That sword is really cool though~

The katana. Think about it, if you have a gun and shoot, it could make alot of noise. Katana doesn't make any noise, so it would be easier to kill someone without attracting others that are playing. Even though I will not kill anyone but if they try to kill me, then I will have to kill that person. :(

Guns would theoretically be one of the most dangerous weapons since they make so much noise. Any dangerous competitors would hear the shots, find you immediately and probably launch a surprise attack. The other weapons obviously make less noise but they're too close range, meaning that anyone with a gun would most likely shoot you before you even get close enough. Which left me with a bullet proof vest and the GPS, and since with the GPS you can see anyone before they're even near to you, I decided to go for that=)
