I would like to suggest some kind of melee and firearm weapon pack to be released in a content update for SOD2 which brings pack fan-favorite weapons from SOD1. This seems to be an even-more appropriate nod to the original SOD now that SOD3 is on the way. I've noticed a few requests in this Wish List section which mentions specific weapons or original character outfits. Possibly putting requests into a "pack" may be an idea. Could be through some specific one-time fan vote or by taking inventory of the most-often suggested weapons and putting them together in a pack. Alternatively, instead of a "pack", could have these weapons added individually with upcoming patches.
My vote is my favorite weapon in SOD1: River Snake w/ Scope. Compares to the Hunter's Model 29 but the River Snake/Colt Anaconda has the prestige of being a Colt revolver with that unique ventilated barrel.
