Survive as long as possible and score as many points as possible while clearing the screens of enemies. Tempest takes place in a closed-tube or open field level, split up into at least a dozen sections. Control the claw-shaped ship that moves along the edge of the playfield, and shoot all the enemies. Advance to the next level when all of the enemies are destroyed. Shoot any existing spikes before advancing to the next level so that you do not lose a life.
