DD1 Redux is a conversion mod of the first Dungeon Defenders video game. It was created by user IHDC who co-develops the mod with Mischief. Both are formal members of the Community Development Team (CDT). Redux is a semi-official continuation of DD1 content updates post-2019. It notably introduces features not found in Vanilla and re-balances the game at a macro scale.

On December 14, 2020, Chromatic Games announced "official branch support" for DD1 Redux. Their post includes instructions on how to download and access the community-developed mod. Prior to Chromatic's post, download and installation instructions were handled on Redux's Discord server.

Gameplay

Ascension (Difficulty)

Ruthless Mode

Integrated (Controller) Emulator

  • Uses the keys F2-F8 to switch between players to control, quick add and remove alt. heroes, and toggle active split screens. The last control hides split screens for Players 2-4 without removing them from the hosted game.

Divine Quality

Tavern Updates

    • Void Shards may be used to craft one of four void weapons. The player may choose to have the weapon selected at random for higher overall quality.
  • The player can change their Tavern's themes to any of the previous thirteen via the in-game Options menu.
  • At the "Diamond Forge," Coal can exchanged for 10 billion mana per piece. Small Coal may be exchanged for 2 billion mana each.

Enemies

Cyclops

Development

Redux was first conceived by IDHC long before his CDT endeavors. He decided to bring the project to life while working on Update 7 in 2019. In their post on the Dungeon Defenders forums website, he describes the mod as (originally): "a different version of Dungeon Defenders (1) that I wanted to play."

In particular, the developers find the Lightning Tower and Wheel O' Fortuna overpowered in Vanilla DD1. Discord user Moose explains that LTs have dominated the "tower meta" ever since they were massively buffed by the CDT. Their main purpose is to kill 'trash mobs,' but the mage tower also attracts Ogres which has become crucial on numerous endgame maps. Lightning Towers were experimentally nerfed in Redux to deal less damage to Ogres; this change was later reverted after playtesting.

IDHC expresses nerfing the Wheel O' Fortuna a very difficult decision to make. To counteract this, towers were given numerous buffs.

As of December 2019, only ID and Mischief are allowed to publish user-generated content that directly modifies the source code of DD1, Redux being an example.

Notes and Tips

  • Ranked Data from Vanilla DD1 can be exported to Redux, but not the other way around.
  • When playing on Ascension difficulty, traditional Ensnare-Electric-Strength Drain aura stacks alone are not enough to kill every enemy less bulky than Djinn, on any mission, without them damaging a crystal.
    • Similarly, auras stacks cannot single handedly kill spiders before they get a chance to fling a web ball.
  • Ogres and/or cyclopes can spawn on the first wave of Ascension missions, with HP in the multi-millions. Bring at least one Jester or DPS hero to deal with them.
  • Like ogres, cyclopes will not attack heroes, defenses or Eternia Crystals blocking their path to a different hero or defense they have aggro on.

Trivia

  • The new Ascension difficulty used to be called "Insanity." Enemies were colored cobalt blue instead of white.
  • "Iron Man" was a placeholder name for Ruthless Mode.
  • In pre-release test builds, Harbingers (which are normally exclusive to Lost Quests) used to spawn during the Sky City boss fight on Ascension.
  • The S.A.M Unit is named after real-life surface-to-air missiles which were developed during World War II.
  • Some of the new maps and challenges in Redux were released on the Steam Workshop. A few of them have been the subject of community-held events through the Vanilla game:
    • Return to Moraggo in 2020.
    • Crystal Cave from October 2-4, 2020.

Cyclops

  • Originally, cyclopes favored attacking heroes instead of defenses.
  • There used to be no mini cyclops. This led to the mob getting stuck at the spawn points in the Servants Quarters.
