The producer of Sonic Forces

<em>Chao Garden from Sonic Adventure 2</em>

Loading

Chao made their first appearance in Sonic Adventure, but took on an even bigger role in Sonic Adventure 2. Culminating to dozens of hours of extra content, the cute creatures had stats to raise, levels to achieve, races to win, and different evolutionary paths based on the the player's interactions with them. The Chao have since been featured sparingly in few Sonic games, having only received cameo appearances in background billboards or dialogue.Though Sonic Forces won't bring back a cute pet simulator, it will mark the return of other recognizable characters. Expect to confront anti-hero Shadow, and iconic villains Chaos 0 and Metal Sonic, who you can see in the E3 2017 trailer above.See 7 Minutes of Sonic Forces Gameplay and read about our impressions of a Sonic Forces demo For more E3 coverage, make sure to visit IGN's E3 hub page
