Rooftop Run (Sonic Generations)

Rooftop Run, also known as Spagonia, is one of the stages of the upcoming game Sonic Generations. This level is part of the original Spagonia from Sonic Unleashed. The stage was revealed at the end of the City Escape gameplay trailer with Modern Sonic flying through it. It is one of the stages featured in the Modern era of the game. Concept art of the Aero Chaser robot was found in the Sonic Generations demo, so it is likely to appear in this level. The Egg Fighter was another common robot found in the original level from Sonic Unleashed, so it is also likely to appear. The Egg Dragoon will probably be this stage's boss.
