How to redeem

  1. 1
    Launch UTDG on Roblox

    Load into a lobby or match where the game menus are available.

  2. 2
    Open the Codes menu

    Codes redeem inside the experience — the Roblox promo-code page won't accept them.

  3. 3
    Paste one code at a time

    Enter codes exactly — no trailing spaces. If a fresh code rejects, rejoin a newer server and try once more.

Free starter cash: joining the UTDG Roblox group adds $100 extra starting cash in every match — worth more early on than most single codes.

Quick game guide

  1. 1
    Pick a stage and place troops

    Enemies follow set paths toward your base — position towers to cover the longest stretch of path.

  2. 2
    Upgrade through the waves

    Waves ramp into tougher zombies and bosses. Spend gold on upgrades rather than spreading thin.

  3. 3
    Team up for later stages

    Co-op lobbies make boss waves far easier — and crates from codes roll extra troops to widen your options.
