Look through some of the sceen shots over at hlfallout.net if you look closely you will see that at the game progressed, so did the skins. The original combine soldiers looked good, but these are BETTER. They changed Alyx's coat, not it is brown with duct-tape on it. And the skins on the Ant-Lions are always changing (is there more than one species) my favorite are the orange with black circles.
Other differences/progressions?...
