All credit goes to Ghosu, whose work I simply tweaked.

Requirements:
Ghosu's Project Flintlock Rifle and any requirements for his mod.

Description:
The basis of this mod is to greatly increase damage done, and decrease reload speeds. I designed it for my Requiem playthrough, so I doubt it has much balance with Vanilla. It is suited for quick combat, in which a few arrows would normally kill you. 
This is my first mod, which I uploaded in case anyone happens to want it. There might be some minor bugs, and if there are, tell me, and I will try to patch them as quickly as possible.
Any tips on how to make things better would be appropriated! 

If anyone else wants something similar, I could likely make another version with a couple tweaks.

Version 1.1 Features:
-Removed all rigid guns
-Removed certain ammo
-Added new versions of guns
-Renamed most guns and ammo
-Changed guns to be very valuable

Note: Reload speed (0.5) reflects that the time it takes to reload a weapon has doubled. So 0.75) means that it is 75% as fast as normal, meaning almost as fast as normal, and (0.25) means 25% as fast as normal, so it takes quite a bit of time to reload.

200 Damage
