They just wanted to re-design it. I like em both. Actually in the videogames there are lots of different aliens, different sizes, shapes, colors depending on what kind of alien it is......Warrior,drone,guard,royal guard...ect. Kinda cool. Like a nest of Ants or something. They are all different depending on what they do.
