Why Chaos Zero Nightmare Codes Don’t Work?
There can be several reasons for a code to not work. And here are the major reasons:
- Launch Phase: Redemption systems may glitch post-launch so update your app or relog.
- Expired Codes: Event codes often last hours or days; check the drop date.
- Already Used: Each code works once per account.
- Typing Error: Codes are case-sensitive; copy-paste to avoid mistakes.
- Server Issue: Ensure your account aligns with the Global server. If issues persist, contact support through the Settings menu or restart the game after updating.
Expired Chaos Zero Nightmare Codes
The game’s too new for expired codes so none have been released yet. As codes roll out and fade, we’ll list them here for reference, including rewards and expiration dates.

FAQs
What Are the Best Agents to Build Around in Chaos Zero Nightmare?
As of October 2025, Rin (S-tier Attacker) shines for her stance-switching burst damage, ideal for clearing tough Chaos Zones. Khalipe (Vanguard) is a tanky must-have, soaking Mental Stress with shields to stabilize runs. Haru (Attacker) offers consistent DPS for beginners. Focus on their Epiphany upgrades via Amplification Anchors.
Is Rerolling Worth It for a Strong Start in Chaos Zero Nightmare?
It’s viable but time-intensive (20-30 minutes per cycle). Clear Chapter 1-2, claim mail rewards (200 free pulls), and hit the beginner banner for a guaranteed 5-star by pull 50. Aim for Rin or Kayron for DPS dominance; if you miss, reset via guest account.
