He repairs the busted bot, and roboticizes Little Planet to create the Death Egg Mk.II, continuing his assault on the world. Station, Eggman pulls out the Death Egg Robot as a last resort, but Sonic trounces it the same as always.Īfter this defeat, Eggman gets the idea to return to Little Planet, where Metal Sonic is still smoldering from his previous battle. When Sonic smashes Eggman's creations once again, he retreats into space, and Sonic gives chase on a rocket. Eggman seeks revenge on his perpetual arch-nemesis by rebuilding his best Badniks to go on a hedgehog hunt. The story is simple: Some time after the events of Sonic 3 & Knuckles, Mad Scientist and aspiring world conqueror Dr. Each episode has four Zones with four Acts each (three standard levels and one boss fight per Zone), plus a final Boss-Only Level in each, making for a decently-sized downloadable game that Sega initially designed to test the waters for classic Sonic's return. It's an Episodic Game, with only two episodes released, though having both episodes downloaded unlocks a short interquel. Sonic the Hedgehog 4 (not to be confused with the SNES unlicensed bootleg game) is a side-scrolling platformer developed by Dimps that is a modern-day throwback to Sonic's roots on the Sega Genesis.
