Updated August 15, 2023 Checked for new codes. Dungeon Defenders 2 is an Action Tower Defense game featured on multiple platforms, where one to four players can work together to protect one or more Eternia Crystals from being destroyed by attacking enemies. The game features classic roleplay game elements such as loot, leveling, pets, and more. The world of Etheria is under attack, and it is up to you and your friends to build up mighty defenses that can burn, freeze, and obliterate your enemies. If that doesn\u2019t work, you can take on the threat head-on and charge into battle yourself. Playing by yourself or with your group, you can level up and equip your heroes, swap them on the fly, and combine their abilities even during combat. Dungeon Defenders 2 comes with the option of entering special game codes, which allow the players to redeem cool free rewards, such as new heroes and gems. How to redeem Dungeon Defenders 2 codes To redeem codes, launch the game and open the Mailbox in the Tavern or the Town Hub. Once you are there, you'll come across a textbox where you need to enter the code and click on the 'Redeem Code' option to claim the corresponding reward.
