Okay I will try my best to expain this. It has been many many many years since I have played it but it is driving me nuts.
You had little green(i thinks) alien guys (i thinks). The object was to get throught each level with as many guys as possible. At the start of the game the all dropped down in a line and they stayed in a line the whole level. You were given a certain number of guys that you were allowed to let die each level to save the rest of them. Of course each level got harder. You may have to build a bridge to save all the guys. There was something in each level that needed to be done to save all the guys. If I think of anything else I will post it but thats all the info I have now.
