phoenix rock and roll half marathon But eventually Knuckles realizes that he was tricked, along with Sonic and Knuckles he's occurring his very own story to get his Master Emerald back from Dr Robotnic who's looking to go. Typical Robotnic. What was really cool about Sonic and Knuckles' game cartrige is you can put other games with it and completely customize the other games! You could put Sonic 2, for instance, within the Sonic and Knuckles cartrige and also have Knuckles in Sonic 2! That definitely changed the complete game, because there were items which only Knuckles had the ability to obtain to. Or similar to Casino Night Zone there was a place rank item you could build a large amount of points with, but couldn't make it as Sonic or Tails. But Knuckles could just glide to the wall, climb up it, and find system and obtain all the bonus points. Not that you had to accomplish this to finish the action, but that managed to get much more fun to work with Knuckles to do this. And to help it become better yet, you might put Sonic 3 within the cartrige and play as Knuckles from his perspective and go through the complete game. And this benefited Sonic and Tails players at the same time, because you might play through your entire Sonic 3 game then go straight into Sonic and Knuckles, that you simply can't even take Tails into otherwise! That really enhanced the Sonic experience definitely.
