Place this in the "ModifiedFiles" folder of the Far Cry 5 Resistance Mod. It only modifies NPC weapons in Hours of Darkness, so it should work alongside mods for the main game. 

Icons for new weapons may not show up correctly in this mod. Also, when you close out of the game, you may lose some items in your inventory. Outside of those issues, Hours of Darkness should work fine with this mod active. Let me know if any problems come up during your playthrough.

Thank you again to mistemitsmit for letting me use his NPC Weapon Replacement mod as a template in making this! Also, thank you again to the Far Cry 5 Modding Discord for helping me figure out several aspects of inventory modding! I hope you all enjoy the mod!
