Use left and right arrows to control, and space to shoot. Always use the green flag to restart. Bases almost entirely off of broadcast commands and variables, so some functions may be glitched when restarted improperly. This game is heavily based off of Space Invaders.
You have three lives. Shoot enought of the aliens to scare off the current wave. When five waves are scared off, the invasion will stop, letting you win. Command has given you three ships to stop the invasion, and you are humanity's only hope. If the aliens reach your barriers, your ship is destroyed and the aliens bring in the next wave.
