Core Defender Support

Open Settings or the Core Emporium Store inside the game and tap "RESTORE PURCHASES". If you are signed in with the same Google, Apple, or Microsoft account used for purchase, your Ad-Free status will be restored immediately.

Characters can be unlocked by conquering battlefields (e.g. Ruined Citadel unlocks the Stormcaller) or by spending gold earned in expeditions in the Heroes tab.

Collect iron, wood, and runes from scouted resource caches across the ruins. Once you discover and link the tower, approach the core and tap or press 'C' to construct fortifications and upgrade energy cells.

Yes! Core Defender is fully offline-playable. All maps, hero progression, forge upgrades, and daily challenges can be played without an active internet connection.
