GUN CREATION SYSTEM

by The UK Cyberpunk Thinktank

 
 

This allows the creation of a variety of new and unusual firearms, by a simple option system to use, follow the steps one by one, choosing one of the choices and noting down the stats given.



 

Step 1:
 
 
    Ammo type
Frame size WA Light Medium Heavy Very heavy Concealability Cost
Pocket -2 10 7 4 2 P 150
Small -1 15 8 5 3 J 250
Medium 0 20 15 8 5 J 350
Large +1 25 20 10 7 J/L 450
Ammo can vary +/- 5 5 2 1



 

Step 2:
 
 
Mechanism ROF Ammo Notes
Break open #barrels * Can fire all barrels at once (1 or 2 barrels)
Revolver +0 6
Bolt action 1 - Usually target pistols
Gas Automatic +0 -
Gas Automatic MP +0 - *
Electric +0 - Electric motor driven and never jams
Electric MP +5 - *
*Machine Pistols can fire at normal ROF with single shots, fire 3 round bursts or full auto at MP ROF 



 

Step 3:
 
 
Propellant Ammo Notes Ammo Cost
Cased rounds - Metal or plastic cased -
Caseless rounds +20% MP's get ROF+5 -
Plastique - High power. Damage +D6  x2
Binary liquid +50% Need mag+bottles to reload. Big muzzle flash -
ETC -20% damage +2D6, ROF=1 Max x5
  NB! Gas Powered and Gauss Weapons not included



 

Step 4:

Medium
.380 auto 2D6-1 A +1 aka 9mm short ROF+1 (max=3)
.38 2D6 A +1
.38 special 2D6 A +1 bullet counts as a 'Tumbler'
8mm 2D6 A +1 ROF +1 (Max=3)

9mm AE 2D6+2 A +1
10mm Auto 2D6+3 A +1
.40 S&W 2D6+3 A +1
 
Heavy
.41 AE 3D6 A 0
.408 S&W Tac 3D6+2 A 0
.45 ACP 3D6 A 0 not 2D6+2 as in CP2020
.357 Magnum 3D6 A 0 not 2D6+2 as in CP2020
11mm 3D6 A 0
 
Very heavy
12mm 4D6 B -1
.44 Magnum 4D6+1 B -1
.454 cascull 4D6+3 B -2 Ammo -1
.50 AE 4D6+2 B -1
.50 Magnum 5D6 B -3 Ammo -1
.577Webley 5D6+1 B -3 Ammo -1
14mm 6D6 B -4 Ammo -2
 
 
AE = Action Express
ACP = Automatic Colt Pistol
S&W = Smith And Wesson

Notes:
.45 and .357 have been upgraded for FID use as the CP2020 figures where too low. The 10mm Auto was designed as a intermidiate between .45's power and 9mm's accuracy and large mag space. This sugested that .45 did more than 2d6+2. This is a personal modification, and can be ignored at will.
Penetration values are on the HARDWIRED quick armour system.
