Retro Tower Defense (RTD) on Roblox is a nostalgic throwback to classic tower defense gameplay, offering a refreshing break from flashy anime-inspired games. While the game is still evolving, players can now enjoy a few working codes in both Retro Tower Defense and Retro TDS—two closely related experiences.

What Is Retro Tower Defense?
Retro Tower Defense is a Roblox experience that brings the genre back to its roots. Instead of flashy visuals, it offers strategic gameplay across maps like Crossroads, HappyHome, SFOTH, and Doomspire. Players summon units using tickets, place them tactically, and upgrade as waves of enemies advance.
Best Units
- Best DPS: Mage, Noli, Hyperlaser Sniper
- Best Farm: Tycoon
- Best Support: Helper Bot, Bling
This loadout will carry you through even the most challenging maps, especially on Hard mode.
