We're not going to lie. We were disappointed to find out that Sonic the Hedgehog 4's "Mad Gear Zone" didn't take place in Final Fight's Metro City, with Mike Haggar teaming up with Sonic to eliminate the Mad Gear Gang.

Instead, we get an industrial-type level with pistons and gears and such, kind of like Sonic 2's Chemical Plant Zone. That's pretty neat, too. We guess. Check it out for yourself after the break. We're sorry we mentioned our Final Fight idea, because now you're as doomed to disappointment with the real thing as we are.
