Dungeon Defenders Redux or DD1 Redux (pronounced /rēˈdəks/) is a large conversion mod of the first Dungeon Defenders video game on PC. It was created by Aydan "IHDC" Edwards 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 a new difficulty level above Nightmare called Ascension which has its own mechanics, loot and progression paths; new defenses, hero abilities, weapons, pets and missions. It also re-balances the game at a macro scale, without completely undermining dominant strategies from Vanilla.

On December 14, 2020, Chromatic Games granted official Steam branch support for Redux. It is now accessed through the "Betas" tab under DD1's properties (done by right-clicking the game in one's Steam Library). Prior to Chromatic's post, download and installation instructions were handled on Redux's old Discord server.

Compatibility with Vanilla

For the first-and-only time the user connects to Ranked in Redux, their full Vanilla Ranked data will be exported to Redux Ranked automatically; the preexisting data is not lost. It is impossible to transfer data from Redux back to Vanilla.

Eternal Defender and all Steam achievements can still be earned through Ranked play in Redux. Only four achievements are incompatible with the new Ascension difficulty level:

  • Can be turned off in the Options Menu.

Divine Quality

  • A quality tier above Ultimate++. Listed stat bonuses cap at 1,099 each.
  • Divine armor gives passive health regeneration to the hero and their non-minion physical defenses every 5 seconds; minions and all non-physical defenses: traps, auras and non-Physical Beams instead have their max health increased by 2.5% per Divine piece, 15% for a complete set.

Void Element and Quality

  • Used to craft Divine/Void Crystals into various items. The Forge Room is accessed through a door on the second floor.

  • Void Crystals may be used to craft one of four void weapons or a new pet. The player may choose to have the weapon selected at random for higher overall quality. These crystals are obtained from completing missions inside the Crystalline Dimension on Ascension, (or Nightmare for the Crystalline Resurgence series).

  • At the 'Diamond Forge,' Coal can exchanged for 10 billion mana per piece. Small Coal may be exchanged for 2 billion mana each.

True Boss Rush

Maps and Missions

Emerald City

    • Defense/Minion Units increased from 120 to 165.
    • Optimized game performance slightly.

Other

Enemies

Weapons

  • Buffed/Nerfed the damage of many map-specific weapons and Monk weapons, primarily those acquired on the new Ascension difficulty level.
  • The displayed Base Damage for many weapons has been changed to better reflect their actual base damage. Weapons affected by this change include the Obsidian Sparus and Gladius.

  • The weapons earned from defeating the Goblin Battlecruiser on Sky City Campaign roll with negative stats far less often.
  • Backstabber's damage multiplier has been increased by 25%.
  • Ban Hammer gives 1.10x movement speed, up from 1.05x.

  • Staves cannot roll above a Charge Speed Bonus of 70-75.
    • This is to prevent most players from accidentally 'overcharging' their weapon which leads to less damage-per-second, due to the kickback caused by unleashing 100%, fully-charged shots.

  • Nessie is awarded for beating the last wave of Dread Dungeon Survival.

  • Squire Guardian stacks with the resistance boost of Buff Beams on affected defenses.
  • Shroomite and Donkey pets can fire up to six (6) projectiles at once and their velocity can be upgraded.
  • Propeller Cat rolls with better stats more often and can now roll up to Supreme quality.

  • Mr. Owl is 15% larger, making him more competitive against his event-only rival: Mr. Crackers.

  • Magic Hat accessory renders bigger by default.

Development

Redux was first conceived by IHDC long before he joined the CDT. Motivated by not wanting the game to die off, Aydan 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 a crucial mechanic to utilize on numerous endgame maps. Lightning Towers were experimentally nerfed in Redux to deal half damage to Ogres; this change was later reverted after playtesting. IHDC expresses nerfing the Wheel O' Fortuna a very difficult decision to make. Numerous towers were buffed to compensate. The team also long considered patching the tower stacking quirk, though ultimately went with keeping it in the game. In their Discord comment on November 5, 2021, Scrub paraphrases IHDC's final verdict to not remove stacking and avoid community backlash.

During a livestream from MrJuicebags in August 2020, IHDC explains some of Redux's general design principles. Two revolve around loss aversion in regards to balance changes. More useless things are buffed than the amount of good things nerfed, whether it be heroes, defenses or items.

Mentioned Features

User Suggestions

Main Article: Redux/User Suggestions

The Redux staff primarily views player/user suggestions that are posted on the DDRnG Discord server.

Reception

While no known articles from professional journalists exist, DD1 Redux has been well-received by the Dungeon Defenders community. Some players argue that this is what Awakened should have been.

However, a few are repelled by its lack of public lobbies vs. Vanilla, stigmatize it as a branch for only endgame grinding or refuse to play Redux because it is a mod.

Legacy

In 2021, Chromatic Games hired Redux creator IHDC into a "game design" position with no further details shared publicly. His experience developing Redux might have caught the studio's attention, but this is unconfirmed. Neither IHDC or Chromatic have explicitly disclosed why or how he was hired or what projects the new employee was assigned to, apart from Dungeon Defenders II updates.

Notes and Tips

Technical

  • Redux does not automatically come with its own .ini configs patched to prevent excessive texture compression/downscaling in-game.
    • A "FixedIni" zip file for Redux can be downloaded off of IHDC's pinned comment in "redux-general" on DDRnG—or >>here<<.
  • It is possible to have both Vanilla and Redux installed on the same PC:
    • This is doable by copying the former game's folder to a non-Steam location before installing Redux.
  • None of the new towers or hero abilities have an assigned hotkey by default.
    • If you want to bind them (or anything else from your hero's Action Wheel), move your mouse cursor over an action, then press-and-hold a number key from 0-9 to assign the defense/ability to that number.

Gameplay

  • 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 any DPS hero to deal with them.
  • Like Ogres, Cyclopes will never attack heroes, defenses or Eternia Crystals directly if they are blocking their path to a different hero or defense they have aggro on.

Gallery

Trivia

  • The Ascension difficulty level used to be called "Insanity." Enemies were colored cobalt blue instead of white (light gray on the minimap).
  • "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 SAM Unit is likely named after real-life surface-to-air missiles which were developed during World War II.
  • Some of the new maps and challenges in Redux released via Steam Workshop beforehand. A few of them have been the subject of community-held events through the Vanilla game:
