Universal Tower Defense Codes (December 2025)

Get freebies like Gems, Trait Rerolls, and Stat Locks in Roblox Universal Tower Defense by using the latest monthly redeem codes for December 2025!

Okay, so I’ve been playing Universal Tower Defense, and it feels a lot like other cool anime-style tower defense games on Roblox. Basically, you collect Units – the stronger, the better – and use them to defend against waves of enemies on different maps. What’s awesome is that instead of grinding for hours to get Gems, you can just redeem codes the developers release. These codes give you free Gems, but also things like Trait Rerolls and Stat Locks, which are super helpful. As a new player, it lets me get some really powerful Units early on, and even as a veteran, I can use the free stuff to make my team even stronger. It’s a great way to boost your progress!
