Besides your basic swords, axes, and knives, there are these.
Boomer
A shotgun that fires grenades. Most hold six shots, but a few have been modified to hold seven. The grenades explode on impact to cause damage, and so do not penetrate a target well. Can be loaded with flashbang or frag grenades.
Blazer
Shoots flames, requires two hands to fire. Some can actually fire a ball or stream of flaming fuel at a target, but this uses up fuel much quicker. Relatively rare.
Vulcan Turret
A heavy turret. It is anchored to reduce kickback, and ammo is fed up into it from stores belowground. Because of this, shooting below a vulcan turret can sometimes cause it to explode. As they are anchored to the ground with ammo below it, they are usually only used for defense of cities or on skyships.
Render
A sword-like weapon that uses spinning razorblades for its edge. Used more often in tree-felling than in battle.
Battery Cannon
A cannon that fires beams of hot plasma. The energy needed to fire is massive, and they are expensive to construct and maintain, so they are usually only found around Universe City. The hot plasma can easily burn through flesh or metal, but even Universe City can only manage the beam for about ten to fifteen seconds.
Pistol
Your basic handgun. Different ammo companies sell different sizes of clips and ammo types. The most common gun. Some have a front mount for a flashlight or knife.
Rifle
Your basic long-range firearm. Like the pistol, it has different clip and ammo types. Comes with or without a scope.
Auto
An automatic pistol. It can use the same ammo types, but it is better to use large clips with it. Some have a front mount for a flashlight or knife.
Shotty
A shotgun, buck or slug. More common than the rifle or auto.
Raven
A two-handed machinegun. Clip sizes range from a large clip to an ammo backpack. Vulcans are sometimes referred to as ravens.
Big Boy
A rocket launcher, holds one round at a time (though rumor has it that some have been modified to hold two). Different rocket types range from your basic rocket to one that pierces armor or splits into four smaller rockets mid-flight. Ammo is expensive, obviously, so those who are quite experienced with them often make their own ammo.
Laserblade
Normally used for metalwork, it is basically a knife that emits energy instead of a blade. The 'blade' can burn or melt through other things. Common in mechanics' garages. Does not last long.
Mjolnir
A vehicle-mounted weapon that shoots lighting. It made its debut in racing, used to fry an opponent's systems, but can also be used to take out closely-grouped infantry. It uses a lot of energy to fire, and so usually has its own mini-generator.
Heat Knife
Despite its name, a heat knife can be any size from knife to sword. It is used on HTBSs. It is made of admium that is super heated to burn or melt through targets. However, the super heated admium is easier to chatter than normal admium would be. They are not very sharp, instead using heat to deal their damage, so they won't cut much when off.
Powerfist
Made of a metal plate that fits over the knuckles. On impact, the plate shoots out on pistons and comes back, increasing the power of a strike. Some have spike on them. Most don't find it useful due to its small range.
Flasher
A flashlight-like weapon that fires a laser used to blind foes. Usually attached to the guns of police for a non-lethal way to disable opponents.
Drelleck #22
A putty-like explosive, commonly known as dough or 22. It sticks to cold objects and explodes from impacts or from a detonator. To use a detonator, stick a receiver to the wall near the dough and push the button on the detonator. Do not stick the receiver into the dough or it may explode.
Drelleck #23
More commonly known as Foam or 23, #23 is a sprayable explosive. When sprayed, it foams upon contact with air, sticking to whatever it was sprayed upon. It explodes when there is a pressure difference from when it foamed, say from impact or wind. Freezing the foam allows safe removal of it, and water dissolves it, making it useless underwater.
