Catch Dragons To Defend: How to Unlock Zones
What is reported about zone unlocking in Catch Dragons To Defend: zones open after pen growth and upgrades, and new zones bring tougher enemies.
Quick answer
Zone access in Catch Dragons To Defend is tied to progression through pen growth and upgrades, not available from the start. Reported play describes catching dragons with Capture Balls, growing the pen they live in, and buying upgrades, then fighting through new zones once the map opens.
New zones bring tougher enemies. A short fire rate bump, such as from a Fire Rate Boost Potion, helps attacks land faster while the player catches up on upgrades.
Exact unlock order, per-zone requirements, and costs are not documented in the reported material. Check the in-game map and upgrade screens for the current gate before assuming a specific zone is next.
