Despite having a rather lukewarm response to Sonic Unleashed, I must confess that I adored the game's Rooftop Run stage. It's one of the few "Modern" Sonic levels that I truly love, and I'm thrilled to see it in Sonic Generations. Between the solid gameplay and the awesome music, it's a fantastic inclusion.
The new screens showcase this stage, alongside Mushroom Hill Zone from Sonic & Knuckles. I also believe that Sonic Heroes has gotten an inclusion in the gallery too. As if all that wasn't enough to tickle your furry boner, there's a brand new trailer right above these words.
