He's here! Who? Sonic the Hedgehog, of course.

Rovio told us that the blue streak would be invading Angry Birds Epic last month and it wasn't a lie.

With the latest update you can unlock the Blue Blur for your fighting team in Angry Birds Epic.

But you better go fast as this is a limited-time crossover event (with Sonic Dash). So if you miss it you won't ever be able to play as Sonic in Angry Birds Epic.

Not only that, but you won't get to fight across the new mini-map. It contains a new Golden Pig Dungeon, two new Chronicle Caves, and other new levels.

Oh, and you'll also get a chance to defeat Doctor Eggman and his robotic minions.

That's not all, either. Chuck now has a brand new class with this update - the Illusionist. Plus, you can raise your birds to level 50 and master classes up to level 12.

This update is available for free, so all you need to do is grab Angry Birds Epic on the App Store, Google Play, or the Windows Phone Store to get involved.
