Duo Defense

Getting Into the Arena

Duo Defense is a browser-based arcade defense game published by OzGames, where quick reactions and constant attention are key. Two defenders stand on opposite sides of the arena while monster waves push in from the center. Your goal is to control the defensive projectile and stop enemies before they break through.

Flow of Each Run

Each run starts in a calm state, giving you a moment to get used to the rhythm of the game. You strike the projectile to clear incoming monsters and protect both sides of the arena. As more waves appear, the pace gradually becomes more intense, and staying focused becomes more important than speed alone.
