Shadow the Hedgehog has a lot of great elements, but somehow they don’t all work together nicely. And without a doubt it's much more serious business than running fast, that's obvious when at first sight when you see Shadow running around with a gun. This is an excellent addition to the Sonic universe lore. Not only is it edgier and darker, but it also has a deeper story with much more plot lines included. When you compare this game with Sonic Heroes or Sonic Adventure, you'll see just how much more complex it is. In his journey, he's trying to find the seven emeralds while trying to find out who are the evil aliens that are destroying the world, but the alien leader, Black Doom, promises to give him back his memories if he finds the emeralds for him. Moved by some of the recent weak memories that torment him, he's also looking for revenge. He's now on a journey to find out who he is, but this title takes place after the events of Sonic Heroes. Shadow is a much more enigmatic character, he doesn't know where he comes from nor where he's going. The world of Shadow The Hedgehog is a much edgier version of the average Sonic Universe, so the speed is still the center of it all, mostly. Shadow the Hedgehog shares some basic similarities to other Sonic games on the series.
