Does Roll to Defend have zones?

Yes. The Roblox description says players can buy and unlock new zones.

Are exact zone costs listed here?

No. Zone names, order, costs, and unlock requirements are not verified in the current public data packet.

Check whether your current units can defend reliably and whether codes or boosts can help the next push.

When reliable zone order and cost data appears, this page should add a table with checked dates and references.

Progression

Plan zone unlocks without guessed costs. The game description confirms buyable zones, while exact zone order and prices remain unverified.

Zone planning

If zombies still overwhelm your setup, improve units before pushing into a harder area.

Coins and brains from public code rewards may help early upgrades, but recheck active code status first.

Do not trust exact zone costs until a reliable table or in-game source is captured.
