An additional weapon mod my deranged mind cooked up:
Restricted Ammunition
+1 Modification Slot
The weapon can only use, or is designed to only use one type of ammunition, like the Slivergun.
The Weapons
The Shortstop Double Whammy
Barret 101
-Barrel Reduction
-Electronic Firing
-Underbarrel Weapon
--UB Barret 101
--Barrel Reduction
--Electronic Firing
--Additional Clip [to get the ammo at the same amount as the top weapon]
The Shortstop does not fire short bursts - It fires Both barrels at once as two separate shots due to the electronic firing being linked. The drawback is that the recoil is doubled but the target takes two separate hits.
Acid Rain
Ingram Smartgun X
-Additional Clip
-High Velocity
-Restricted Ammunition - Capsule Rounds
-Electronic Firing
The Acid Rain is designed to fire a withering hail of capsule rounds usually filled with highly corrosive acid [Acid Rating 6]. A critical glitch with said weapon destroys the gun (It melts and sprays corrosives all over the place) and the user takes a basic hit from the weapon.
The Assured Kill
Ballista
-Burst Fire Mod
-Additional Clip
-Restricted Ammunition [Direct Fire Missiles]
The Face Filler
M79B1 LAW
-Short Barrel
-Underbarrel Auto-Assault 16
--Bayonet
