We are unable to provide additional keys for Campaigns, Quests, or Missions.
Keys are handled by Publishers so it would depend on them if they want to give creators additional keys or not.
While we cannot assist with that directly, we encourage our creators to reach out to Publishers and Studios with their ideas if they think additional keys can have a positive impact on both sides!
If you need an additional key because your Key Kit contains a code that has already been used, please make sure to contact our support channels!
