If there was such a thing, it would be a series of tables to "easily" cross reference gun makers, the parts they use, and the range of attribute bonuses said parts will add to the base statistics of the gun.
well I am not like your dad. I worked as a chef at TGIF-Mattson
you're kidding right??? 11.5 MILLION GUNS... is that even possible. I thought I seen a video a long time ago which a developer said there were 700+ weapons... but c'mon... 11.5 million cannot be right... but if it is... GOD DAMN!!
Its because the game has an interesting feature called Gearbot, which takes all the variables for each type of weapon, using a randomized selector to pick different weapon attributes, such as damage, manufacturer, bonuses, etc.
