Sonic the Hedgehog 4: Episode I is a platforming video game released developed by Dimps and Sonic Team for the Wii's WiiWare service. It is billed as the successor to Sonic & Knuckles on the Sega Genesis/Mega Drive. Designed to be similar to the classic Genesis games, 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 & Knuckles.
