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:

Caliber	Damage	PEN	WA	NOTES

Light
.22 short	D4	0	+2
.22 long	D6	0	+2
.22 long rifle	D6	0	+2
.22 magnum	D6+1	0	+2	ROF-1
5mm	D6	0	+2
6mm	D6+1	0	+2
.25 ACP	D6	0	+2
.32	D6+2	A	+2
7mm	D6+2	A	+2

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	2D6+1	A	+1	aka 9mm parabellum
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.

Step 5:

Calibre	Base ROF	Notes	Machine Pistols	MP Notes
Light	3		30
Medium	2	3 with heavy frame	20
Heavy	1	2 with heavy frame	15
Very heavy	1		10	Not recomended

Step 6:

Quality	Reliability	WA Mod	MP ROF
Low	UR	-1 or 0	-5
Normal	ST	0	0
High	VR	0 or +1	+5

Step 7:

Cost modifires

Mechanism	Electric	+75
	Other	+0


Quality	UR	-50
	ST	+0
