Astro Blaster

Astro Blaster is a one or two player arcade game where you have to blast various waves of different alien ships who appear above your ship. On each screen a wave of aliens will appear and you have to destroy them all to move onto the next screen and a different wave. Each wave moves in different formations and fires lasers at you but you also have a laser and can fire back as you move your ship left and right at the bottom of the screen. The ability to warp is also included which slows down the enemy for a short space of time. You need to keep an eye out on your laser temperature gauge, fire too much and it overheats, disabling the ability to fire for a short time. Another gauge to be aware of is your fuel gauge which slowly decreases. To fill it, you have to dock with your mother ship. This appears after every four waves so the quicker you destroy the waves, the quicker you can dock. You have to line up your ship as it approaches. It is game over if you lose your three lives or run out of fuel.
