Sega has today released a list of the 20 games that it's planning to show at E3 next month, 10 of which hadn't been announced previously. One such game is Sonic Heroes, which is currently in development for the PlayStation 2, GameCube, and Xbox. The game is described by Sega as Sonic's biggest adventure yet, and it will include a new configuration feature that will allow players to control three characters simultaneously. The team-based gameplay will allow players to employ Sonic's speed, Knuckles' power, and Tails' ability to fly as they explore massive worlds.

We'll bring you more information on Sonic Heroes when we report live from E3 on May 14-16.
