Dragon Defender

Hold the keep against a dragon siege. Loose arrows at diving whelps, fireball-lobbing drakes, swooping wyverns and frost dragons, shoot their fireballs out of the sky, and topple the Elder Dragon every fifth wave. Chain kills for combo multipliers and choose a new boon after every wave.

Controls: Aim with the mouse, click to fire where you point, hold then release for a piercing power shot, SPACE to call a volley, 1–3 to pick a boon • Touch: tap to fire, hold to power up, Volley button
