Soul Calibur IV. You may recall SCIV as the weapons based fighter that features not only ridiculously proportioned female fighters but also Yoda. The Playstation 3 version gets Darth Vader himself, though he may be Force choking his way to the 360 if rumors are to be believed. Also on the release this week are Spectral Force 3 and Summer Athletics The Ultimate Challenge. Spectral Force 3 is a Japanese strategy RPG and Summer Athletics The Ultmate Challenge is ... well, honestly, we have no idea. Looking at the title, we'd say someone is looking to cash in on the Olympic Games.
