Well, I think, everybody knows that alpha/beta versions of Postal 2 was slightly different in some features. Like em: weapons, peds (models and skins), sounds, maps, etc.
So, what we have today?
Yeah, we all know about "Original Shotgun" from alpha version of Postal 2, which was introduced later in "Eternal Damnation" and then in "Complete.
Then I have founded the old weapon pack from "Wolve" (hand meshes from beta, and alpha pistol's hand mesh and texture).
Then - "KarmaData" folder. You can find some beta models of Postal Dude, Female NPC, Gary, SWAT, and etc., and of course you can port it into original game.
AND - "ChameleonSkins2.utx" - texture pack, included in "Complete" version, you can find a lot of old-alpha skins of NPC's.
So I gotta question, RWS. Do you have more of alpha/beta content? It's really freakin awesome.
Im still pretty sure that the "old" Postal 2 was more violent and more atmospheric.
