I dunno. It looks okay, but there are a lot of companies out there that do "slightly" futuristic soldiers. Unfortunately they all do them in metal and they aren't cheap.
Will wait on Corporation proxies until I start seeing an assortment of pics of Mantics actual models.
EDIT: I did not realize the Defiance Marines were cast in hard plastic.
