Mercenary Keep: Siege Defense

Castle defense with a living wall. Hold your keep against waves of bandits, undead and witches: tap enemies to focus your crossbow, raise a 5-second Shield Dome against red-marked heavy blows, throw Fire Pots and unleash Crown's Wrath. Every boss has its own move you can see coming. Grow the keep floor by floor, hire named mercenaries, man the ballista and lead short hands-on expeditions.

Enemies come from the right. Your heroes fight on their own; tap or click an enemy to focus your fire on it. Shield (W) holds 5 seconds against red-marked heavy blows, then waits 5 seconds; Fire Pots (E) hit dense groups; Crown's Wrath (R) is your big strike. Read each boss's wind-up and press the right button. Spend gold on upgrades and floors, and survive as many waves as you can.
