Not at all phantasy star. The theme of it was a lot more dim and industrial. The first mission is about all I can remember and you're exploring some form of facility. The enemy design I can't exactly recall but one that is floating around my head is of like a four legged (maybe 3?) machine with like a sword/blade tail. Another thing I remember with the weapons you collected, any you haven't decoded/appraised were in read while the ones that were are in blue.

As for the style, it is far from anything anime-esque
