CZN progression has three connected jobs: develop combatants, build useful run loadouts, and use those loadouts in the content you want to clear. Start with the problem blocking you. This index gives a short route for each job before linking the detailed steps.

Starting or returning

New players should follow the tutorial and Growth Guide, concentrate materials in a working team, and learn AP and stress before pursuing a perfect saved build. Returning players should check current notices first; old event rewards and exact launch-era unlock routes are not permanent promises.

A fight is failing

Read enemy intent and action counters, then check whether the team lacks damage, AP/draw, or protection from health damage and stress. A card upgrade cannot fix a sequence that never reaches the necessary card. Compare the card variant and its trigger, not just the character name.

Progression or a saved build is missing

Simulation material stages, Chaos loadout farming and Sortie progression serve different goals. Farm the material blocking the next useful upgrade, or choose an eligible Chaos/Codex for Save Data. Sortie itself does not export a run loadout. These distinctions follow the dedicated mode guides linked as sources.

You have a code or a tower question

A Build Preset string goes in the matching combatant's Cards > Build Presets menu; it is not a reward coupon. For Spiral Tower, plan sustained damage and recovery around the published mode rules. Basin of Hyperspace is a separate mode.

Installation or account access is the problem

Use the supported store/launcher route, then diagnose the exact launch or patch symptom. Account switching is separate from unlinking or transferring a login provider.
