What's up with the predator?

On the top left corner, where you see the predator, it keeps changing(same thing with the alien). And then sometimes you see the predator with a gold mask. Is that one of the predators in AVP2, is it from a game, or is it from a director's cut of any of the two predator movies(if they had any)? You'll find it eventually. Just keep going back and forth between forums and you will find it. Please correct me because I could be wrong, it could just be the helmet reflected from the sun in the picture.
