After some tweaking here and there, I managed to do the impossible. I created a FULLY automatic shotgun in GTA IV.
Basically this mod includes a Shotgun with a very high rate of fire, which shoots faster than an assault rifle. Forget the AA-12! This is the real auto shotty you've been looking for! Surprisingly, this has never been done before and I am happy that I am sharing it for the first time. Since it's a shotgun that shoots extremely fast, it causes devastating damage in the process. It replaces the Baretta and it's ready when you are, chief.
*This mod automatically comes with the Red Army Mod by 1/4 Life, and I am aware that this mod already exists on this site, but I cannot release the edited text in the WeaponInfo as that file is very sensitive and fragile. I do not want others trying to edit the file themselves as it doesn't always work, but I am sure that it will work if I upload the whole file. I hope you can respect this decision I have to make*
So this mod will be including faster rates of fire on all guns since it is part of the Red Army Mod. However, I made A few tweaks of my own to the values for the other guns. I give all credit to 1/4 Life for creating the formula to make guns have faster rates of fire. Which is what inspired me to use it to tweak a shotgun which has never been done before.
I am very grateful to be sharing this with all of you and I hope you enjoy having a faster, more powerful shotgun in the GTA experience. Have Fun!
