Undertale Adventures TD Codes [QOL] (September 2025)

Join the battle in Undertale Adventures TD! Put up defenses and use codes for boosts. Don't let the monsters get through!

Do you play Roblox and do not pass by Tower Defense? Then Undertale Adventures TD is right up your alley. In this game you defend your base from waves of monsters, and the heroes from the legendary Undertale help you in this. The battles come one after another, and your task is not just to survive, but to make your defense as powerful as possible. To make it a little easier for you to start (or a little more fun to experiment), the game has codes that give boosts, coins and other goodies. By the way, on our site you will find not only codes for this game, but also for other projects in a similar theme – Undertale Timeline Reset codes, Undertale Final Showdown codes and Undertale Dungeons Go Beyond codes are waiting for you if you are interested in anime games, fighting games or other popular Roblox-genres.

Where to find Undertale Adventures TD codes

If you want to be the first to get all the latest codes, check out the official developer communities. First, this is the Side Productions group – they periodically publish new products there. Secondly, be sure to check their Discord – they often post codes there a bit earlier than anywhere else.

What is this game even about?

Undertale Adventures TD is a tower defense with a soul. The plot and characters are inspired by the atmospheric Undertale, but now you have to use your favorite characters not for negotiations or one-on-one battles, but to build defenses and stop the waves of enemies. Each wave gets more and more difficult, and that’s where pumping comes into play. You can boost your units with traits, which are special abilities and buffs that make your army truly invincible. Do you want Sansom to take out dozens of enemies or put Papyrus in the rear to hold the wave? It’s possible here.

Tired of your units draining on the fifth wave? Learn to combine their abilities, experiment with Trait and build your own unique strategy. And yes, the graphics and music are referenced, so Undertale fans will feel right at home.
