Overview:

This mod adds 45 weapons (and three uniques!) made by Millenia and MTindle. All of them have had their damage, health, weight, value, etc. rebalanced to fit better into vanilla New Vegas. All of them have been integrated into appropriate leveled and perk lists. Some of the weapons have had their meshes and sounds fixed. Also, all the weapons have had their names changed to conform to the naming standards of Fallout 3/New Vegas.

A patch for hitman47101's Anniversary Anims Pack is included here.

Notes and Credits:

Millenia has opened permissions for people to use his mods (see second image), as long as you don't monetize them (that includes donation points). If you'd like to make a patch for this mod, respect Millenia's wishes and do not monetize it.
Some weapons unfortunately couldn't be included due to underlying problems that I am unable to fix. If you see that a Millenia gun has been omitted, it's for a good reason.
I'm not a guns expert, nor a Fallout lore expert, so if the names don't make sense, please, do let me know your suggestions. Same goes for balance and leveled list integration, I tried my best to make them fit vanilla, but it's not gonna be perfect.
As for credits, well...

Millenia, MTindle, Naky and everyone else who worked on the original weapons - for the amazing weapon mods
Hitman47101 - for the Anniversary Anims animations included in the patch
Qolore7 - for the inspiration to make this and his amazing Viva New Vegas guide that got me back into the game
yRaven - for failing his mission
xEdit team - for their invaluable tool, which was used to make this mod
RoyBatterian and everyone else who made GECK Extender - for making the tool usable so I could edit scripts
Obsidian and Bethesda - for Fallout New Vegas
The Snigclave - for their contributions towards the great land of Snigeria
Polar - for being a piss boy
You - for checking this mod out

Special credit goes to Ytera, who's hatred for the RU-556 and CZ805 keeps me motivated to keep them in the pack at all times

Unique hint: the guy who had it didn't quite make it past a vault and definitely didn't bring enough antivenom.
The other two uniques don't have a spawn yet, you'll need to use console commands to get them. WeapTG18cUnique and WeapMB500SB are the IDs.
