In FO3 I had a mod that renamed every weapon in the game with the name of their real life counterpart, is there anything like that? I also had a mod called Apocalypse Armory that added a crap ton of new weapons, Looking on he nexus I see a lot of individual weapon mods but are there any weapon compilation mods like Apocalypse Armory?

WMX is the mod that most people use on this game. It fleshes out the ability to mod the weapons in nice ways.

Heck, it's not like there is a lack of weapons in this game. You should see my Weapon Wall in the Underwater Hideout that is displaying all the Vanilla Weapons in the game.

There are renaming mods, but I can't recall what they are called.

Aside from WMX and WME which are basically just adding modkits to existing weapons, there's Classic Fallout Weapons (adds all types of weapons from the original games, added to leveled lists, vendors, and a few uniques placed in the world), AG's Supplementary Uniques (unique ranged weapons of all types and tiers placed throughout the wasteland), 20th Century Weapons (an FO3 port, don't think it's actually completed but is probably useable), STALKER Weapon Pack (adds weapons from STALKER games to a new store), AKs & AR-15s Weapons Pack (a pretty comprehensive mod adding many variants to leveled lists and vendors), the Book of Earache (script heavy real world weapons with working attachments like under-barrel grenade launchers, fancy tacticool sights, & other such improvements, added to a new store), ZL Armaments (basically the best of the STALKER weapons, an Adaptive Combat Rifle, and other stuff added to a new safehouse), Ahztek's Shrapnel (never used but supposedly one of the better packs of real world weapons, probably not up to date if you can even find it), and there are packs on the nexus from more prolific weapon mod authors such as scottmack, micalov, and camon. Millennia's many custom weapons are supposedly going to be released as a pack in the future.

And on top of all that there are some mods that add craftable weapons such as Homemade Grenades (self-explanatory), Mad Science (basically adds new weapons and gadgets recipes to the game based on completion of vanilla quests), Homemade Weapons Pack (a small pack of 4 mesh edited/mashup weapons but defo worth checking out), and Bingles Melee Weapons (everyone has an effect like cryo damage, plasma damage, etc.).
