Role Playing Weapon Creation System

Standard Metrics

Because the original system was designed around the GURPS system, there are some standard assumptions that need to be extracted in order to convert the design for use in other game systems. Additionally, it's needed to recognize how those same assumptions are applied in the other games systems.

GURPS:
1 inch of unsloped hard steel = 70 DR
  • 20 dice of damage will penetrate about 50% of the time

This is a computerized version of the weaponry sections of Steve Jackson's GURPS Vehicles (2nd Edition, ©2000). It is intended to streamline the process by allowing the user to make the relevant descisions and make the computer calculate the statistics. The end results are copy/paste-able as text into whatever document the end user requires.

Due to the single-system source of the calculations, there are certain terms and assumptions sprinkled throughout the process. System specific terms (i.e. "Technology Level") have been kept to a minimum, but attempts have been made to explain or hide them in the end results. Sections of game-specific statistics are provided, and it is hoped that more will be added.

Due to the generalities inherent in a "comprehensive" system, it will often be impossible to match the specific statistics of a real-world device or the stats published in a game system. It is not unreasonable to vary the numbers by 20% in either direction in order to provide uniqueness among firearm models and to provide differences across the time period selected.

Slugthrowers

Slugthrower Creation

These weapons use a chemical propellant or energy impulse to launch a solid projectile out of a barrel. These weapons include anything from the hand cannons of the 13th century, to modern tank weapons, and through ultra-technology electromagnetic catapults.

Beam Weapons

Beam Weapon Creation

These weapons use energy to excite certain kinds of particles and then projects them down a barrel. The excited particles may be photons for lasers, ions for particle beams, plasma, and more exotic applications.

Launchers

Launcher Creation

Launchers fire self-propelled munitions, such as missiles, torpedoes, and rockets. These might be guided by the launcher, by the projectile itself, or perhaps not at all.
