Friends become foes when Captain Dread's crew questions Sonic's loyalties. Then, a battle on the high seas breaks out over possession of the Shard.

The key to reassembling the Paradox Prism lies in one of the Shatterspaces. But can Nine and Sonic find a portal to safely transport the Shards there?

To get help in the fight against Nine and his winged lackeys, Sonic heads to New Yoke and forms an allegiance with the very last people he ever expected.

To beat the biggest bot on the battlefield and get one step closer to Nine, Sonic needs to move fast — and accept a little help from his friends.
