You are a commander of a space ship. Your mission is to take your spaceship to the other side of the universe, to a place called the "Stars." There, you will find a lot of planets. On one of them, you will find a lot of alien ships. Your task is to shoot them down, using all the weapons you have. 

You can use two types of weapons: missiles and lasers. You can also use a "Wormhole" to travel to the next level. You will find a lot of new weapons and enemies on each level. 

You will also find some new spaceships. Each time you complete a level, you will get more ships and more weapons. 

You will also have an option to play in the "Survival" mode.
