From the instructions:
If you survived Galaforce then you may have the necessary skill and daring to succeed in Galaforce 2.
The aliens attack in precise preconceived formations, with each Galaxy comprising several such formations. There are a total of 16 Galaxies. You must pilot your spaceship, carefully avoiding the aliens, or shooting them whenever possible. Some aliens need to be hit more than once to destroy them.
Watch out for the alien Capsules. You collect a capsule by colliding with it or by shooting it twice. You will then gain a special feature. Some features are helpful, e.g. extra laser power, extra life; others are harmful, e.g. no firepower, slow ship movement.
