These five codes represent the current active roster for The ROBO Studio version of Multiverse Tower Defense. Copy each code exactly — uppercase letters matter. Redeem through the Shop menu by scrolling to the bottom text field and pressing the green Redeem button after meeting the five-win gate.
MTD is the starter code advertised on the Roblox game page itself, making it the most widely tested and reliable reward source. Cash fuels your first summon sessions at the Summon building. Combine MTD with early story clears before spending on banners.
Undertale-themed codes drop during the active universe event. UNDERTALE and 2K_LIKES_UNDERTALE provide crates with elevated rates for event units. Read our Undertale event coverage for banner timing and unit priorities before opening crates.
YOUR_PERSONAL_HELPER_FRIEND injects 25 Magic Crystals — valuable for enchant rerolls at Gambler X without grinding AFK Chamber. RELEASE grants Shiny Kuzy, a tradeable Shiny unit with marketplace value on the Trading Plaza.
When codes stop working, they move to our expired list. Rejoin a fresh server if a brand-new code fails — hotfixes sometimes delay activation across all instances. Never use third-party code generators; they are scams targeting Roblox accounts.
