I found these weapon replacements made me enjoy using all of the game's weapons rather than just a few, so I packaged up my favorites for you guys to try out.

EDIT: The last version of this pack had custom sounds that were causing sound-related bugs. This new version has some of those sounds ripped out to fix that.
