I am not a modder, (I stopped modding when I was 14 with Empire Earth) Although I do play on PC, my girlfriend is currently using my PC for a extended video editing project/job. Due to this, I am currently playing FO4 on Xbox One and I don't know if this mod already exists, but I would like to post my ideas anyway!
1. More variety of handguns (bring back 9mm ammo)
a. M1911 style + mods (.45 Pistol)
b. Beretta M9A1 style + mods (9mm Pistol)
c. Desert Eagle style + mods (to make use of .50 cal for pistol users)
d. MAC 11 style + mods (9mm SMG)
e. Grease Gun style + mods (10mm SMG)
2. Change all of the synth weapons completely, instead of fat white trash laser weapons, make them sleek and more advanced!
3. Make a SPAZ-12 style shotgun that uses slugs instead of bird shot! Or make any shotgun capable of interchanging ammo.
4. Make it so that we can hook up codsworth to a power armor station and customize him. Like giving him power armor paint jobs, or crafting a claw for one of his arms that allows him to pick up and use any weapon you give him.
5. Allow clipping to be turned on and off easily in the settlement editor.
6. change the current Assault rifle to use .308 ammo and make that ammo more common, then create a new line of 5.57 Assault Rifles.
a. US Assault Rifle (M16 style, burst shot by default. Mods include RIS rails and attachments, and full auto and semi auto)
2. Also Modifiable to shorter M4 style, doing this increases ROF and lowers range.
b. Chinese Assault Rifle (AK-74 style, full auto by default. Mods include single underside rail, and semi auto fire)
1. Also Modifiable to shorter AK-74U style, doing this increases ROF and lowers range.
7. More mods for the minigun, it is totally outclassed by the gatling laser! It needs a mod that changes ammo type to 10mm, slows ROF more, and
does high damage like the gatling laser mod.
8. More legendary Perks! like one called "Mass Multiplier" that increases body shot damage!
If I think of more I will edit them in!
