Blasters for Everybody! 0.0.1
This script will basically replace all NPC weapons with blaster weapons!
You will find two files inside the .zip, just choose one and drop it on Grand Theft Auto V/scripts folder:
BlastersForAllPeds.cs: give just the UnholyHellbringer (assault rifle/SMG – like)
BlastersForAllPeds[plus]MinigunBlasters.cs: give the UnholyHellbringer or the Widowmaker (blaster minigun)
Important! these blaster-like guns were introduced in GTA V as part of an online update, so your game must have that update!
