Gigalopolis Zone

Gigapolis Zone, second zone in Sonic Chaos, is another fairly easy stage, where you fight many familiar enemies. The only challenge comes in the ridged platforms, which often leave spikes underneath. The boss of this level is an oversized caterkiller which tosses its body parts all over. This boss is significantly harder than Turquoise Hill Zone's boss.

In the original Japanese version of the game, "Sonic & Tails", this zone is called Gigalopolis Zone.
