Egg Rocket Zone is the sixth zone in Sonic Advance. The level starts outside, on some kind of rocket-launching platform. Once you enter the rocket itself, it will take off, causing the time counter to start counting down from 4 minutes 59 seconds. You'll have to make it to the next part of the rocket where part of the rocket comes off and the rocket moves even higher up before the clock counts all the way down. If you make it in time, then the clock will be set back to 4 minutes 59 seconds. There's a total of three segments to the rocket, making this level and act the longest in the entire game. The goal at the end of the third segment is the entrance to the next level, Cosmic Angel Zone.
The outer areas of the first and second segments of the rocket are abundant with bottomless pits, making those places incredibly dangerous. The third segment, which is up in space, include the famous gravity reversal feature seen in Sonic & Knuckles' Death Egg Zone.
