Topic: Weapon Balancing
It seems that the weapons are unbalanced in strength based on how they are obtained. The hammer can easily get a person 2-3 kills per spawn when used in junction with the chain (to latch onto enemies or to quickly get to an enemy), and the handgun seems useless since it does 1 damage per shot. The Shotgun and Missile launcher could also be a bit stronger too, they feel a bit weak for being a weapon that you can't always have. The sword though seems the most balanced, although i think it shouldn't hit so many enemies at once (killing 5 players with one swing!).
In short,
Hammer is too strong for being a starting weapon
Handgun is too weak compared to all other weapons
Shotgun and Missiles could be stronger.
Ninja Sword shouldn't be able to kill so many targets with one swing, but I don't mind it as is.
Edit: You could just have it so the handgun has unlimited ammo, but less fire rate too.
