What's inside

Castle Eras, the free 3D lane battler at cybermaxtools.com/games/castle-eras/, stays free: the 10-level campaign and the Daily Battle are for everyone. Campaign+ adds a second campaign of 10 levels (11-20) with new commanders, Endless Siege (hold your keep against waves that keep growing, with your best wave saved) and a Hard mode for every campaign level. It never changes the replay-checked daily board or anyone's score there. One payment, no subscription; your order code turns it on on any device. 14-day fix-or-refund.

Refund policy

Yes. If it doesn't work as described, email us within 14 days and we fix it or refund you in full. See the refund policy.

Is checkout secure?

Card details go only to Stripe. CyberMax never sees them; sales tax or VAT is calculated at checkout.

Stripe sends you straight back to Castle Eras with Campaign+ on, and your receipt arrives by email. The order code on the receipt page turns it on in any other browser.

Why not Kingdom Rush - Tower Defense or Bloons TD 6?

Published prices, checked 2026-10-29: Kingdom Rush - Tower Defense, $9.99; Bloons TD 6, $13.99. Those are whole games. Campaign+ is a $6.99 expansion for a game whose first 10 levels you can play free first, so you know exactly what you are buying.

Does Campaign+ change the Daily Battle or its leaderboard?

No. Everyone plays the same daily battle with the same rules, and the server re-plays every posted score from its taps. Campaign+ only adds levels and modes, and Endless Siege scores stay on your device.

Is it a subscription?

No. One payment of $6.99, yours for good. A CyberMax Fun Pass or Arcade Lifetime already includes it.

Why not just play the free version?

You can: the 10-level campaign, the Daily Battle and every crown look stay free. Campaign+ adds ten harder commanders, Endless Siege and Hard mode.
