Crisis City is a stage in the upcoming game Sonic Generations. It will represent Sonic the Hedgehog (2006) in the Modern Era of the game. The boss of the level will be the rival battle with Silver the Hedgehog. As well as the fact that Metal Sonic will be the boss of Chemical Plant and that Shadow the Hedgehog will be the boss of City Escape, Silver will be the boss of Crisis City. Iblis's minions are also very likely to return in this stage.
This is likely part of an alternate timeline as the events of Sonic the Hedgehog (2006) were negated due to the ending of it.
- This is one of the only stages in Sonic Generations to come from an alternate timeline. The other is Stardust Speedway, which is set in the Bad Future.
- The remix from this stage is very diferent from the original version, it's more heavy, but still sound like the original.
- This stage is the only one that is also a boss stage. It's also the only place where Sonic and Silver never met each other. However, Mephiles did show Silver what Sonic looked like here.
- One of the balls of debris Silver throws contains a "Chaos in Space III" sign.
