Earlier this year at Mobile World Congress, NVIDIA and Sega announced Sonic 4: Episode II would be coming to TegraZone in an optimized version for NVIDIA's Tegra 3 hardware. Today the promise became reality as the $6.99 game is now available via NVIDIA's TegraZone on Tegra 3 devices. The timing alone is pretty special. While the Xbox Live Arcade version of the game debuted yesterday, the iOS version won't come out for another day and the standard Android build will take another month. NVIDIA's ability to pull even small day long exclusives over iOS is still impressive in a world where many game developers put no one ahead of Apple.

The final game seems a lot like what we played at MWC in February. It works on all Tegra 3 devices using either on-screen touch controls or an external gamepad. The gameplay is distinctly Sonic, although I'll admit my fondness for the platformer peaked years ago. The single player game has you controlling Sonic with an AI controlled Tails. Also included is a multiplayer mode that allows for co-operative play over Bluetooth. The game looks good on Tegra 3. We've been running a preview APK on some as of yet unreleased hardware so I won't comment on performance just yet.

NVIDIA promises better visuals in the Tegra 3 version of the game than the standard Android version due out in the coming weeks. While we don't have the standard Android build, NVIDIA sent along some screenshots to show the difference in image quality.
