## What is Crystal Bastion?

Build a defense worthy of Crystal Bastion.

Protect your castle along fixed enemy routes. Choose your towers, plan your upgrades, and spend battle gold wisely as you hold out through twelve waves.

A campaign with lasting progress
Explore seven handcrafted levels. Earn treasury gold, research new towers and abilities, and save your loadout before the next challenge. Research unlocks your options; each battle still rewards careful building and spending.

Make your own defense
Discover fifteen buildable tower types, twenty-six passive abilities, and three active skills. Bring up to four tower types, six abilities, and two active skills into battle. Study enemy behavior and adjust your strategy as the campaign unfolds.

Play at your own pace
Pause when you need a break, switch between normal and double speed, or save an unfinished battle and return later. Normal, Hard, and Nightmare difficulties offer new goals after your first victory.

Offline single-player play
Your progress stays on your device. No ads, in-app purchases, or developer account are required. Optional Apple Game Center achievements report your local accomplishments; they do not restore or synchronize saved games.

Choose from English, Simplified Chinese, Japanese, French, German, Russian, Korean, Spanish, and Italian in the game settings.
