With this method it has always worked, first download the mod (NTerraria 6), then you have to locate the terraria folder which will be in steam apps > common. Next unload the contents of the mod into the terraria folder and you can create a shortcut for NTerrara 6 or simply add it to the Steam library. It should be playable also note that steam has to be open in order for the mod to work If you don't not own a legit copy ill link files you'll need to put into your terraria 1.3 folder Simple: NTerraria 6 > Terraria folder > Launch Steam > Launch Mod
