Sonic X Shadow Generations

The new campaign follows Shadow the Hedgehog and runs parallel to the events of Sonic's story.

The Threat: Shadow's old nemesis, Black Doom, has re-emerged. He plans to take over the world by exploiting the time distortions caused by the Time Eater.

The Journey: Shadow is pulled into "White Space," where he must relive signature moments from his past (such as the Space Colony ARK and Rail Canyon) to thwart Black Doom’s plans.
