About Mercenary Keep: Siege Defense: Castle Defense with a Living Wall
Mercenary Keep: Siege Defense puts you in command of a keep under constant assault from bandits, undead, and witches. The core idea is a "living wall" — your fortification grows floor by floor as you push back each wave, and named mercenaries join your garrison along the way. Short hands-on expeditions break up the siege, and a ballista adds another layer of firepower to your defenses. Every boss telegraphs its move before striking, giving you a real chance to respond rather than simply absorb punishment.
How to Play Mercenary Keep: Siege Defense: Survive Waves and Grow Your Keep
Enemies approach from the right. Your heroes fight automatically, so the active decisions fall to you: focus fire on a specific target, time your defensive abilities, and read each boss's wind-up to press the correct counter. Gold earned along the way goes toward upgrades and new floors. The goal is to survive as many waves as possible.

- Crown's Wrath: your most powerful strike, used for high-impact moments
Controls
- Tap / Click enemy: focuses your crossbow fire on that target
- W: raises the Shield Dome
