Sonic & Tails 2

While Doctor Robotnik was testing his last weapon of destruction, one of his assistants made a grave mistake, resulting in five of the Chaos Emeralds spreading throughout Mobius. Sonic and Tails have to get the five Emeralds of Chaos before Doctor Robotnik, but this is not only his rival: Nack the Weasel (also known as Fang the Sniper) does not seem to be an ally of the hedgehog and the fox, like Knuckles , tricked by Robotnik.
