Its fun but gets boring.
It has good graphics and the sound is good too. When you play as Shadow you meet some character like Sonic, Tails, Amy and more good characters and even villans to stay with you and guide you. The good characters are playable on the player 2 controler so it could be some good help. There are soooo many levels to complete! you could use guns or meel weapons. There is 2 player mode but you could only use shadow and his androids.
THE BAD
You can only play as Shadow in the main game, the other characters are only playble for the P2 controler. Its not very cool doing the levels again and again. And I found that the missions are kinda hard for me. The story has alot of confution. When you play the game for the first time its very fun but when you play it alot it stars to get a little boring. You can be good or bad in the game but its really nothing intresting.
