Where to Get New Ultimate Tower Defense Codes
New codes usually ride on something happening, a big update, a holiday, a player-count milestone, or a giveaway Ghostworks decides to run, so the drops cluster around those moments rather than arriving on any set schedule. The first place they surface is the Ultimate Tower Defense Discord server, specifically the announcement posts, where the devs tend to bury the actual code behind a spoiler tag; you have to click it to reveal anything, which trips up more people than you’d expect. If picking through Discord history isn’t your idea of a good time, the list above gets refreshed every day, so it’ll catch the same codes.
