Terraria Tower Defense Codes (June 2026)

Terraria Tower Defense is a Roblox tower defense game developed by Monster’s Games, built around the pixel-art world of Terraria. Players collect and forge units, equip them with weapons and accessories, then hold the line against escalating waves of enemies and iconic bosses. Codes deliver Coins, Crates, Hammers, Fallen Stars, and other consumables that give your roster a direct, tangible push forward.

Where to find new codes

Monster’s Games releases codes in response to milestone visit counts and player totals, alongside major content updates, and occasionally as goodwill after unplanned downtime. The official Terraria TD Discord is where new codes are posted first, making it the most reliable place to catch them before they expire. The game’s Trello board is also worth keeping an eye on — it lays out current unit details and upcoming content, which tends to signal when a larger update (and the codes that accompany it) is on the way.
