I use either Wasteland Armory (og and or slav version), Scavengers Spoils, or Smorgasbord since theyre pretty makeshift-y and scavenged looking guns that mostly fit the wasteland/apocolypse settings i use them for. (especially Wasteland Armory but it and the slav version are abanoned and needs some touchups that'll likely never come). I also use ISAWC for inventory since its one of the only inventory mods that allows you to put props in your inventory. And lastly npcDrops so npcs actually drop props not available in the map. almost all of those mods are pretty much abandoned so ill also be looking at the reccomendations for anything better. https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1244116107&searchtext=wasteland
