XP codes grant 500-1,000 experience toward your account level, and one specific code delivers a direct level-up instantly. Seasonal Candy codes (such as TRICKORTREATV2) reward Halloween event currency for the event shop, and cosmetic codes unlock skins like the Tweet Skin. Match Booster codes also appear in the catalog. With 43 total codes released across eight years, the game has one of the deeper code histories in the tower defense genre.

New codes are announced via the Cosmic Development Twitter/X account and in the Cosmic Development Discord server, with seasonal drops tied to Halloween and Christmas events and milestone codes marking game anniversaries. The developer's naming style - IMPOOR, THESEDARNKEYS, NUKELAUNHCODES - gives the catalog a playful personality that makes each new code announcement notable.
