SEGA has literally only shown us about five seconds of gameplay for Sonic the Hedgehog 4: Episode 1, but some one was nice enough to leak over a minute worth of gameplay and some screen shots that reveal how many and what zones will appear in Sonic the Hedgehog 4: Episode 1.
The video is recorded via a offscreen camera and is a alpha build of the title. You can kind of hear the music, but you will probably need to turn your volume up.
The screenshots show off the start menu as well as listing for four Zones in the game. The zones included are “Splash Hill Zone”, “Lost Labyrinth Zone”, “Casino Street Zone”, and “Mad Gear Zone.”
You can check out the screen shots over at 1Up and the leaked footage after the jump, but if the video is removed you can still check it out over on 1Up as well. *Update* Footage re-embeded from Gametrailers.com
The first episode of Sonic the Hedgehog 4 is planned to hit sometime this summer on PSN, XBLA and WiiWare.
