A good score depends more on thinking clearly and staying calm rather than on lightening reflexes. There's a hall of fame for anyone getting a good score. The fines get heavier each time they're given. These are space stations, rockets and satellites and they all belong to you. If there are many of them then they quickly become deadly. These are spikers and they're just a pain. Their shields will regularly drop for a moment which gives you the chance to destroy them. Instead they stop your shots while allowing alien shots to pass through which is probably worse. These are alien shields and they don't shoot back so relax. Best to avoid them like the plague but, if you really like a challenge, you'll earn 10k for killing one. They fight like blazes and they're almost impossible to kill. You can tell when motherships are going to appear as a little tiny mothership will appear near your time bar. Every 200k (if you ever get that far) you'll get the chance to pick super weapons. Every 100k you'll get 3 bonus ships on screen at once. Be careful which power up you choose as some are more useful than others. The choice of power ups appear at the top of the screen. These get harder to kill as the game progresses. Green meanies are worth 5000 credits but they take a lot of hitting and they fight back to.

None of the aliens like to shoot near the bottom of the screen. Be aware that these little critters will split into 5 separate aliens when hit. There is one variety that permanently changes colour. If this starts to turn red then it's best to stop firing and let everything cool down. There's a weapon temp gauge under the time bar in the top right. Hold the fire button down for continuous fire but be careful not to overheat your weapon. If you're quick then you can earn a bonus. You have limited time to destroy each wave and a time bar ticks down in the top right hand corner. You are armed with a mobile canon, limitless ammo and limitless bravery. You are based on a wandering moon and are our last defence.

The swarm have invaded our solar system and now control every planet.
