"Sonic the Hedgehog has been running for 20 years. Surely he's getting a bit tired now? Not at all, says SEGA - and this anniversary game is a true celebration of all the adventures the blue blur has been on in the last two decades. What's more, both Classic Sonic and Modern Sonic are on hand to tackle these past stages, across three distinct eras of franchise gameplay. That's right, our athletic up-to-date hero meets with his retro, dumpy (and silent!) counterpart for the very first time. Some kind of time paradox merges their worlds together, and the finger is immediately pointed to series villain Dr. Eggman. But, while the 'good' doc is relishing in the chaos, he's not actually behind the chronological meddling - some dark shadowy creature is the real culprit, and the blue duo have to work together and fix things. Playing as Classic Sonic offers silky smooth controls and a satisfying level design that works with a dynamic camera to give the feeling that you're not just navigating a 2D space - truly representing classic Mega Drive play as you remember it. As Modern Sonic, you'll be darting through re-interpretations of past stages in 3D at an exhilarating pace. Seeing these retro stages from the perspective of a totally new hedgehog will give you a true blast from the past!"
