Have you ever played alien shooting games where you are the spaceship and you must kill the aliens coming towards you? Well Galaxians is that kind of game. To play you will use your arrow keys to move left or right. To fire at the aliens coming towards you press the space bar. You have to try and kill all the aliens but you must be careful. The aliens do fire back at you and they do start to come closer. Once they get to a certain point they will begin to move faster and if you aren't careful you can get hit by them and die.
