In this newly revamped game, you control a space ship and your task is to protect the Galaxy from alien space invaders. The alien spaceships will shoot at you back and will keep coming closer to you while moving from side to side faster and faster to have you miss them. If you shoot at the alien Mothership (protected by a team of smaller spaceships), it will drop some valuable weaponry which you have to collect with your spaceship. Your weaponry will be temporarily upgraded by giving you extreme shooting capabilities. Weapon upgrade is not time-based but instead is limited by the number of shots. Once the limit is reached – your regular weaponry is enabled.
