How to Redeem Codes in Retro Tower Defense

Sadly, the Retro Tower Defense code redemption system hasn’t been implemented yet. It’s a much-requested feature, and the developer did mention that we may get it down the line. When that happens, rest assured you’ll be able to get all the codes on our list, together with a tutorial on how to use them.

Best Towers in Retro Tower Defense

While we’re waiting for the RTD codes to come out let me show you some of the best units in the game. You need a top-tier damage unit with one AOE-focused and another single-target for boss killing. You also need a good support which can be an off-DPS or a buffer like Helper Bot. Lastly, you want a farm Tower to generate cash so you can upgrade faster. Here are the best units in Retro Tower Defense:

• Best DPS Units: Mage, Noli and Hyperlaser Sniper.
• Best Farm: Tycoon.
• Best Support: Helper Bot and Bling.

These will be a dream-team and will carry you in all maps including on Hard.
