The sequel fans have waited 16 years for is finally here - Sonic The Hedgehog™ 4 Episode I!

Featuring enhanced gameplay elements, including the classic Sonic Spin Dash, and the versatile Homing Attack, Sonic 4 picks up right where Sonic and Knuckles™ left off.
Two exclusive levels built specifically for play on the iPhone & iPod Touch using the accelerometer.

All of Sonic's classic moves are available, including the newer Homing Attack which will add a new level of control and excitement.

Race through 4 unique zones containing 4 acts each as well as 7 special stages.

A staple of the Genesis-era games, the special stages return allowing fans to collect the 7 Chaos Emeralds and unlock Super Sonic.

Dr. Eggman returns with new and improved mechas and will go berserk when he accumulates damage.

GamePro - “…this looks and feels like a genuine Sonic game, deserving of the "4" attached to its title.”

IGN – “After an afternoon in its presence it's become seared in our conscience just like the classic levels of the early Sonics – and surely that's reason enough to have faith in Sonic the Hedgehog 4.”

Cleanest update to date!

I swear SEGA is on a roll with these updates on the Sonic 4 ep games! Please SEGA, if you do just this one thing is that you give us Sonic 4 ep 3 to end off the trilogy? Like the Sonic 4 games are good and not bad as what people make it out to be. You have done well with these games and I love both of 100%. So if you can, please give us Sonic 4 ep 3? It will be so good and add Knuckles in it as well if you guys weren't going to. But back on topic, this update looks clean. Just the buttons seems a bit small. So if you fix that, that'll be great. Btw, thanks for updating the both Sonic 4 games!

This game, is not good

Don’t let the title fool you, despite how well done Sonic 1, 2, CD, 3&K were, this one only dreams to be as good as they were. First of all, the mobile version, is probably the worst version. While they did update Sonic’s model in this version, the controls and UI are horrible compared to the console variants. You can see the outline on the text saying “Please tap the screen.” This just shows how hastily slapped together this was. The game itself, yeah it’s not good. The graphics are awful, it’s not that they are using Modern Sonic, it’s the fact it all looks so glossy and had no effort put into it. Level design is ridiculously questionable. Compared to past classic sonic games, this one makes no sense! Levels go on for way too long. Also they go on for 3 acts. The themes are completely stolen and unoriginal. Splash Hill is just Green Hill from Sonic 1. Casino Street is just Casino Night from Sonic 2. Lost Labyrinth is just Labyrinth Zone from Sonic 1. And Mad Gear is just Metropolis Zone from Sonic 2! Nothing is original! Neither the bosses! They are just stolen from Sonic 1 and 2! So if you are thinking about buying this game, don’t. Skip this one, and go play Sonic Mania instead
