Bubble invaders are attacking the planet. Help the one-eyed alien to break all nuclear balloons in order to save his planet. There is nothing forbidden in this mission - use power ups, hide behind platforms, fire bullets. Make sure no balloons are left! You can play in 1 player mode or 2 player mode with timer or no timer
