Unique to Space Invaders :
1) The saucers that run across the top of the screen shoot back at you when they have a clear shot.
2) Some invaders split into two invaders on either side of the original, giving you more invaders to shoot.
3) When you finish a rack, the following gets printed on the screen : "Well Done Earthing, this time you win. Now do battle with our super forces".

Large Invader : 10 points
Medium Invader : 20 points
Small Invader : 30 points
UFO : 50 to 300 points
