Blade

Blades, or more accurately, melee weapons, require no ammo, but require you to be standing by the target.

They are Secondary Weapons and include
 * Knife
 * Club
 * Stun Baton
 * Katana
 * Axe

Damage is usually high, but they are the most difficult weapon to use - and the AI is usually better with them.

Not a great weapon to have in capture the flag, but a weapon you may not be able to avoid in a gun game.
