The deadly invaders are once again threatening Earth. Beaten off the first time, they have regrouped their modified ships into the familiar attack formation. Only by blasting them out of the sky, as they swoop toward you, can you save the world from destruction. This colourful sprite game will keep you and the kids amused for hours. To get it running; type in listing 1 which is the Basic part of the program. Save this onto a blank tape. Don't rewind the tape after it has saved. Type in listing 2 which is the machine code file creating program. When this runs without errors it will save a machine code file onto the tape after the Basic program on the tape. It is probably a good idea to save the machine code creator as well, on a seperate tape. If you have made a mistake typing in the numbers you will be told which line to correct. If you have made a major mistake in the data you will get a Type Mismatch Error. To find out where the error is type "PRINT LN", the number which appears on the screen is the approximate linenumber for the error. Once you have got the game working, the controls are Z to move left, X to move right and SHIFT to fire the laser.
