Sonic fans have been getting spoiled with loads of live stream segments on Sonic Forces and Sonic Mania today. Although Sonic Mania has been largely old news, Sonic Forces has been a gold mine of new details. IGN’s Sonic Forces segment continued the trend with new details and even new gameplay showing off the Custom Hero in Green Hill, including a battle against a huge boss. We’ve included video of the segment, a fan’s video rip, down below. The new gameplay begins roughly 6 and a half minutes in. Feel free to check it out, if you want.
