It's alright. Interesting approach to the story with multiple endings. All three mission routes in each level fall in line with Shadow's character so you can choose which side you think he'd take. The levels are fairly short so you'll most likely want to do multiple routes. But the missions where you have to defeat 30, 40 or more enemies are a bit of a slog. In fact, I don't think most missions or levels are interesting enough to replay to make going through 10 endings worth it. If you do a couple routes sticking to the missions that are easier you'll have a good time. Shadow controls pretty well; a tad slippery, but an improvement over Sonic Heroes. The use of weapons is neat as well. Gotta respect the direction they decided to go with for Shadow's story, the edginess makes this game standout (among the Sonic series) and worth taking a peek at.
