How to Play King of the Monsters
Quick start
Choose a monster and defeat the opponent in each city arena. Reduce its health, collect power-ups from successful grabs, and pin the downed monster for a three-count. Use buildings and aircraft as weapons, but keep moving to avoid military fire and the opponent’s charge attacks.
Controls
D-pad: move in eight directions. A: punch; near a downed opponent, attempt a pin. B: kick; beside a downed opponent, pick it up. C: run forward; double-tap away to retreat. A+B: jump. During a clinch, follow the directional prompt and attack to win the throw. Mash buttons to rise or escape a pin. Start pauses.
