The gameplay in Universal Tower Defense is what you might expect from this kind of thing: you need to protect your base from waves of enemies. In order to do so, you create a dangerous path for them by correctly placing your warriors.

There are also various quests to complete and a few modes to try out. If you need a little help to progress and are on the hunt for codes, you're in the right place. Below, you'll find a complete list of active codes for Universal Tower Defense. They will grant you useful rewards, such as Gems and Rerolls, which will help you summon better characters.
