While them Brainers were busy foolin' around Jackstown, we Runts spoke to some good people there about more practical things. Like guns. When we'll be able to use all this great stuff, Cap'n?
CLASS-0/LT: Light Guns
Most common, still too strong for frail vehicles.
CLASS-1/HV: Heavy Guns
Powerful weapons, usually turreted, mounted on heavy craft.
CLASS-2/MS: Missiles
External mountings. Cannot be used on ground vehicles.
CLASS-3/IB: Internal Bays
Internal. Same as MS, but more of them rounds.
CLASS-4/DV: Divebombing Weapons
Rely on craft's own momentum and vector to deliver payload to target.
CLASS-5/GR: Ground/Slow Craft Weapons
Cannot survive supersonic speeds.
CLASS-6/AA: Anti-Aircraft Weapons
Dedicated ground-to-air weapons. Usually modified LT or MS.
CLASS-7/BR: Broadsides
HV, but more. Maximum firepower. Very exciting.{ALT}
