Your aim is to fly heavily armed spaceship and destroy aggresive enemy units in each sector to proceed to the next one. Use your ARROW KEYS to move around and press "Z" KEY to fire your plasma gun and press "X" KEY to fire a missile. Be careful, your lives are limited. Be sure to pass the checkpoints before the timer runs out. You will earn power-ups or gold for shooting down each enemy ship. You can use collected gold to purchase shields and missiles upgrades. Enjoy!
