German website giga.de has posted a video featuring 30 minutes of gameplay from Sonic Generations! In this you can see the hub worlds, unseen parts of levels like Chemical Plant, and other things which I won’t spoil here. It might be a tad spoileriffic for some of you, but definitely worth a watch if you’re on the fence about Generations.
UPDATE: The video has been removed, likely due to the accidental reveal of Speed Highway posted above. If they reupload the video, I’ll update this post with the new link. Sorry for any inconveniences!
UPDATE #2: Video is back, courtesy of ikethehedgehog on Youtube!
