Sonic the Hedgehog has been running for 34 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 three and a half decades. What's more, Shadow has joined both Classic Sonic and Modern Sonic to tackle this sprint through the blue blur's glory days. Sonic X Shadow: Generations brings the 2011 classic to a new audience with brand-new Shadow content. That's right, our athletic up-to-date hero meets with his retro, dumpy (and silent!) counterpart for the very first time, and in celebration of his appearance in the Sonic 3 feature film, Shadow's got sucked up into it all and gets his own brand-new campaign. 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. Meanwhile, Shadow and Sonic '06 must confront Black Doom and Shadow's own dark origin in a series of breakneck stages full of heartstopping action and high octane set pieces. Back in the original Sonic Generations levels, things have been touched up a little. 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!
