Ironhold - Idle Tower Defense

One castle. Endless waves. Every rebuild starts higher than the last.

Ironhold is an idle tower defense set in the world of Thornveil, where you command a single keep across an unending siege. Place your defenders. Route your gold. Watch the walls hold — or don't. When the keep falls, the coffers fill, and the next siege begins stronger than the one before.

This is a game of small decisions that compound. Every coin picks a lane. Every upgrade sharpens the loop. Every run teaches you where the walls will break next.

WHAT YOU'LL DO

— Defend across endless waves. Wave 40 is not the end. Wave 400 is not the end.
— Recruit from eleven great Houses. Fifty-five named defenders at launch, each with their own strengths and their own price if they fall.
— Route your gold across attack, defense, and support. Every siege is a new economy.
— Rescue what the walls take. When a defender is captured, you can send others to bring them home.
— Return to progress. The keep works while you're away — resources, waves, and stones accumulate offline.

WHAT MAKES IT DIFFERENT

— The roster stays with you. Named defenders level up, remember their wounds, and carry your history across every run.
— The Veilwatch turns each week. New invasion scenarios, new leaderboards, new pressure.
— Twenty-eight artifacts to unlock, each one bending the siege in a different direction.
— No timers standing between you and the next decision.

Ironhold is built for players who want the depth of a strategy game and the pace of an idle one. The walls will fall. That's part of the loop. The chronicle is what you build across every rise and every ruin.

Hold the line. Rebuild higher.
