Warzone 2100 has a diverse spread of weapons available, and they are unique enough to make their classification difficult. They can be classified on the basis of targeting type, upgrade family, role, etc. The classification shown here will be mainly on the basis of broadly-defined roles.

Machine Guns

Machine guns are cheap, simple and relatively low-tech rapid-firing weapons that do low damage, but have a fast rate of fire. They are best used against numerous light targets, like Scavenger units and Cyborgs. They struggle, however, against heavy tanks, whose armored Tracks and high Kinetic Armor ratings deflect most of the damage dealt by machine guns.

Machine guns can be mounted with equal effectiveness on anything, and are available from the very beginning of the game. All iterations of this family are simply a stronger version of the same concept. Lasers eventually take over the anti-Cyborg role in the late game.

Cannons & Mass Drivers

Cannons are a simple, versatile class of weaponry. They are most effective against tanks, but do well against most other targets also. The Light Cannon, Medium Cannon and Heavy Cannon have moderate range, damage, and rate of fire, with the Hyper Velocity Cannon having extra range but lower hit points and the Assault Cannons having a higher rate of fire but lower damage.

The mass driver family is a direct evolution from the cannons at a higher technology level. They do more damage and have longer range, but this is still moderate compared to other contemporary weapons.

The main strengths of this weapon family is it's versatility and it's high durability, which make cannons and mass drivers excellent main battle tank weapons well suited for heavy combat.
