📋 About This Mod
MOD IS DEAD. SORRY EVERYONE.
I just don't have the time to work on this and there are other mods that do similar things now. I should have announced this earlier than I did, but I was too proud to really admit to myself that it wasn't just 'on hiatus' it was dead, and it has been that way for a while. I won't be deleting it or anything just in case someone still wants these files, but the mod isn't going to be worked on anymore. I thought about and even began creating a new version of this mod from a blank slate. I had made some pretty good progress on it too, but now I have been trying to make my own games and if I have free time then it feels like a waste to not work on an indie game project to me right now. I hope you all understand.
ORIGINAL DESCRIPTION:
Inspired by CaliberX!
Requirements:
Far Harbor DLC
Nuka World DLC
What is New Calibers?:
New Calibers is primarily an ammunition database of sorts. It adds a large amount of new types of ammo to the game, everything from the humble 9mm Luger to the large . 500 Nitro!
New Calibers also is a weapon mod database. It adds a large selection of mods for the vanilla firearms. It also uses a set of new keywords to do this so simply adding the proper ma_ to a custom weapon (along with the attach point from AWCKR) gives it the full set of mods to access. In addition it adds a bunch more keywords and mods intended to be used by custom weapons. For example, the ma_9Pistol is intended for 9mm handguns to use. See the section called "weapon mods" for the full list!
-- Misc mod items will be in a separate plugin due to possible lack of realism transferring a mod from one kind of gun to a different one (coming soon)
It also adds a two new guns from re-purposed vanilla assets. The PPK and the PSL Rifle.
Install Notes:
- For newcomers there are no concerns, just put into data file manually or use NMM, doesn't matter.
- For those upgrading (prior to v3. 06), you will lose any pipe bolt-action caliber mods you may have (as they now use the same item as the hunting rifle and those mods no longer esxist). Don't worry I added one to my game, made the change and loaded it just fine. The gun will be intact except for any swapped caliber.
