Sonic The Fighters (XB360) | Sonic Playthrough p.4
Part 4 of 4 - Sonic the Hedgehog (Sonic the Fighters) playthroughs. (Xbox One / Xbox 360)
This fight against Metal Sonic sorta a bit overpowered by most of its attacks, the claw attacks and the spinning tackle... But once its defense "barrier" guages is all emptied, then he'll be defenseless and easily vulnerable to be defeat fast. (Just still watch for those powerful attacks...)
Once you've finally defeated that boss character Metal Sonic, there'll be a scene where you'll face the secret final boss with time limits and one round, Dr. Eggman! (aka Dr. Robotnik) In this pit match, you have about 16 or 15 sec to beat him and you've been an automatic Hyper Mode by the chaos emeralds granted its power onto you. You need to be quick to take down this evil mad doctor to claim victory, but I'm not sure if there's a different ending depends on how you win or lose to this timed battle, so I'll see if I could do a different playthrough next time.
