Sonic the Hedgehog 4: Episode I is a platforming video game released for the Wii's WiiWare service in October of 2010. The first of several intended episodic releases, it was co-developed by Sonic Team and Dimps, and is billed as the successor to Sonic and Knuckles on the Sega Mega Drive. Designed to be similar to the classic Sega Genesis/Mega Drive series, Sonic 4 combines the traditional 2D gameplay of classic sonic games with 2.5D graphics and new gameplay elements. Players control Sonic, running, jumping, and defeating badniks through levels at high speeds. They may also use power-ups such as the iconic speed-up shoes, barrier shields, and invincibility. The game also features special stages where the player must go through a maze, based on the special stages from the original Sonic the Hedgehog, to find the seven Chaos Emeralds; the reward for this is the ability to play as Super Sonic in normal levels, not seen since Sonic and Knuckles.
