Description

The purpose of this game is to fly through the solar system and reach Earth. The other planets that have you travel to before Earth are Neptune, Uranus, Saturn, Jupiter, and Mars. It only takes two warps to arrive at Neptune, but all others including Earth take three warps to get to. Each time you reach a planet, there is a Challenge Stage where you try to destroy as many enemies as possible. After reaching Earth, there is a Challenge Stage followed by a very fast "three warps to Neptune" stage. After this, the levels and the background music start over.

How to Play

The majority of enemies are spaceships, which must be destroyed to complete a level. They appear either from the centre of the screen or from one of the edges, and move in swirling patterns. They can shoot the player's ship or destroy it by contact. They hover near the centre of the screen after completing their deployment pattern, and occasionally fly outwards and shoot at the player. If not destroyed by the player, the enemy ships gradually fly away one by one.

There are also several other types of enemies: satellites, asteroids, and laser beam generators. These appear intermittently and soon disappear of their own accord if not destroyed by the player.
