Duet Night Abyss codes (December 2025)

If there’s one thing that makes Duet Night Abyss stand out among similar games, it’s that all the characters can be obtained for free. No luck required, and no stressing over whether or not you’re getting a 5-star after saving up.

To really get the most out of your team, though, you’ll still need plenty of resources — and that’s where redeem codes come in, providing everything from currencies to Combat Melodies. So, read on for a list of all the active Duet Night Abyss codes and how to redeem them.

Updated December 1, 2025, to confirm code validity. No codes were found, and none expired!

Active Duet Night Abyss codes

There are seven active Duet Night Abyss codes you can redeem right now. Many of the launch rewards have expired, but the ones listed below can still be claimed:

Here’s a brief explanation of what each reward can be used for:

• Phoxene = Rare currency
• Carmine Globule = Enhances Demon Wedges
• Coin = Common currency 
• Weapon Manual I, II, III = Provides weapon EXP
• Combat Melody I, II, III = Provides character EXP

These rewards were shared by the devs just before the game’s launch, but if you also pre-registered before, you’ll receive extra freebies on top of these. As more are released, we’ll update this page — so bookmark it and check back soon

How to redeem codes

You can redeem codes through the in-game settings. However, this option won’t be available until you encounter Berenica in the cave, right after the dream sequence at the start of the game.

When you get there, all you need to do is follow the steps below to access the code redeem page:

1. Select the three-lined icon on the top left of your screen.
2. Click the cogwheel icon.
3. Head over to the Settings/Miscellaneous tab.
4. Scroll down to the “Redemption Code” option and click on it.
5. Enter the code.
6. Hit Confirm.

Once that’s done, you’ll get a little pop-up confirming your rewards. They’ll go straight to your inventory, so don’t worry about checking your Mail.

The only thing you need to keep in mind is to enter the code as-is, as they are case-sensitive.

Are there any expired codes?

There are no expired codes yet at the time of writing, but if we spot one, we’ll be sure to add it to this list.
