Sonic x Shadow Generations

Shadow the Hedgehog is back with Classic and Modern Sonic in SONIC X SHADOW GENERATIONS, an all-new collection featuring two unique experiences!
When a mysterious creature creates time holes in their universe, Sonic and Shadow each set out on a high-speed action adventure!

In this new standalone campaign, Black Doom—Shadow's nemesis—reemerges and threatens to take over the world. Shadow must journey into his past in order to save the world.

When Dr. Eggman and the mysterious Time Eater rewrite history, they scatter Sonic and his friends across space and time. Now, Modern and Classic Sonic will have to team up in adventure where past meets present!
