E.G.G. Station is the fifth and final Zone of Sonic the Hedgehog 4: Episode I. Most of this Zone is a boss rush against the four main bosses of the game, only this time, they can be beaten with less hits than before and the first and second boss use their newer attacks earlier while the third and fourth bosses only uses their second phase attacks. After defeating these bosses, Sonic runs after Eggman as Eggman hops onto his Death Egg Robot, which of course looks like the final boss of Sonic the Hedgehog 2 and has the same attack patterns. After the player damages the robot enough times, it goes berserk, thus making it much more difficult to defeat Eggman.
