Galaxians

Galaxians is a fixed screen shoot 'em up, most similar to Galaxian. Lately a number of freighters have gone missing and scans show that alien ships are present in the area. Now it's up to the player to seek out and take out these subversive life forms. Like in the original arcade game, the player controls his ship left or right at the bottom of the screen and shoots toward the aliens above him. The aliens start in stationary positions, but at times they swoop down towards the player and attacks. The player gets points for each killed alien. The amount of points awarded is based on how close to the player they are. After a wave of aliens has been killed, the player moves on to the next level and the difficulty increases.
