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.”

Very pleased with updated version!

I brought this game many moons back when i had a 3GS and it has looked very dated since retina display came out. But not any more! Looks and plays great now on my iPad! Thanks for this update Sega. Now can we have sonic 3 & Knuckles plse??

Good but crashes

This would be 4 stars if it wasn't that it crashes on my iPod on the last level in space. Not as good as the original sonics so its not going to be 5 even after the problems but is worth it if your already a sonic fan. Please fix the crashes.

No Username Is Good ,


I don't why people say it doesn't work - just turn off your device and turn it on and play the game - it's easy as pie.
The game is great and enjoyable to play and it's a good game.
