+Achievements, Items or Inventory:
+Create a folder named steam_settings right beside steam_api.dll if there isn't one already. In that folder, create a file named items.json and/or achievements.json which will contain every item/achievement you want to have in your game.
 An example can be found in steam_settings.EXAMPLE that works with Killing Floor 2.
 The items.json syntax is simple, you SHOULD validate your .json file before trying to run your game or you won't have any item in your inventory. Just look for "online json validator" on your web brower to valide your file.
 You can use https://steamdb.info/ to list items and attributes they have and put them into your .json.
