What are Codes in UTD?
Universal Tower Defense features a Codes system which allows players to earn valuable rewards by redeeming them. These codes are typically released by the developers to celebrate milestones (like likes or visits), updates, or real-world holidays. Rewards often include Gems (for summoning units) and Trait Rerolls (for buffing your team).
