Chaos Zero Nightmare Endgame Progression Explained: How to transition after story

After the main story, Chaos Zero Nightmare’s true endgame loop revolves around Chaos Manifestation → Zero System → long‑term Save Data and gear building, with events and Trauma/Promotion content supporting that core. The key transition is hitting Captain 40 to unlock Zero System, then shifting most of your time and stamina into that mode instead of basic Chaos.

Step 1: Finish story, unlock core systems

Once credits roll, you should stabilise your account and tools before no‑lifing Chaos.

Clear Promotion Missions and main Chaos
- Story actually progresses through Promotion Missions; finishing them unlocks higher Trauma, Memory Fragment dungeons, and Chaos stages for replay.
- Each chapter introduces one Chaos fight; beating it once adds that area to Chaos Manifestation for farming.
Use Arc City facilities
- Arc City becomes your endgame hub for:
  - Research Facility (progression trees and passive bonuses).
  - Affinity events (dating for stats/rewards).
  - Psychotherapy (reset Mental Breakdown stress for your agents).

This is your “setup” phase: make sure your core roster is promoted, Potentials started, and Arc City systems online.

Step 2: Push to Captain 40 and unlock Zero System

Zero System is the game’s true endgame mode and goalpost for early post‑story play.

Why Captain Level 40 matters
- Game8 and multiple creators confirm Zero System unlocks at Captain Level 40, even though it’s positioned as endgame.
- A progression guide explicitly says: once you clear the level‑25–30 hump and hit 40, “put most of your playtime and stamina towards farming [Zero System] as it becomes the replacement to the Chaos.”
How to get there efficiently
- Do daily events and clear event shops; they’re time‑limited and shower you with EXP and upgrade mats.
- Spend Aether mainly on growth content (Promotion/Trauma, Memory Fragment dungeons) and some Chaos Manifestation to strengthen Save Data; this pushes both account level and unit power.

Once you hit 40, your endgame focus shifts away from generic Chaos to structured Zero System runs.

Step 3: Learn and prioritise Zero System

Zero System is a roguelite ladder that upgrades both your account and specific characters.

What Zero System is
- It’s described as “the endgame rogue‑lite content”: two‑floor runs similar to Chaos Manifestation with map nodes, events, and bosses, but tuned for higher difficulties and better rewards.
- Runs grant Chaos Orbs that feed the Chaos Matrix track with crystals, units, EXP, partner EXP, and crafting materials like Multi‑Dimensional Alignment for high‑end Memories.
Codex difficulty ladder
- Zero System uses Codex seeds at Difficulty 1–10; clearing a Codex grants new, usually higher‑level options.
- Endgame progression advice is to steadily push Codex difficulty upward (e.g., D1 → mid tiers → D8–10), since higher levels give better Save Data caps and Chaos Orb income.
Where your time should go
- Multiple guides stress that after unlock, Zero runs should consume the bulk of your playtime and stamina, because they effectively replace classic Chaos as your main long‑term mode.

At this point, “progression” largely means climbing Zero difficulty and upgrading your best Save files.

Step 4: Build and farm endgame decks (Save Data focus)

Endgame power is tied to Save Data quality per character, not just raw levels.

Save Data as permanent power
- Each character has Save Data that stores cards, Epiphanies, and passives unlocked in Chaos/Zero runs; higher‑value saves mean stronger starting decks and stats.
- Endgame players farm specific Zero difficulties (e.g., D6+ on preferred Codex) to build “endgame decks” for a few core carries, then branch out.
Efficient deck farming
- An “efficient endgame deck farming” post asks what difficulty to farm; responses focus on staying where you clear reliably and get high Save values, then moving up once that tier becomes stable.
- You don’t need D10 immediately; a stable D6–8 where you consistently finish both floors without resets is often better value than shaky D10 attempts.
Who to invest in
- A piloting/planning guide recommends deciding who is your carry and who sustains your carry as the universal account plan, then building Save Data and gear around those cores first.

The post‑story grind is essentially “pick 1–3 mains → stack their Save Data via Zero → sprinkle upgrades on supports.”

Step 5: Integrate events, Season 2 systems, and side content

Finally, fold in seasonal and side systems that enrich or diversify the endgame loop.

Seasonal Chaos and weeklies
- Seasonal “Galactic Disaster” and similar events layer extra Chaos‑style content with weekly point caps (e.g., 8,000 points), rewarding more Chaos resources and unique items when cleared quickly.
- Endgame players often schedule a few fast Seasonal Chaos runs each week alongside their Zero laddering.
Future Season 2 systems
- The 2026 roadmap teases additions like Spiral Tower, expanded Archive, Guild Office, Zero System upgrades, and Save Data presets/borrowing, all aimed at diversifying endgame activities and making Save management smoother.
- Balance updates promise to lift underused builds and controllers rather than nerfing strong ones, preserving investment value in top characters like Tressa and Cassius.
Daily maintenance loop
- Event clears and Trauma/Promotion for mats.
- Memory Fragment dungeons for gear.
- Zero System runs for Save Data, Chaos Orbs, and Codex climbing.

Viewed as a whole, Chaos Zero Nightmare’s endgame progression is a Zero‑centric roguelite loop layered on top of daily farming and seasonal Chaos: finish story, unlock Zero at 40, climb Codex difficulties, build a few powerful Save Data decks, and then use events and upcoming systems (Spiral Tower, Guild Office, presets) to keep that core loop rewarding over time.
