A fourth Sonic XG preview has been uploaded by Joseph Waters, also known as Nitemare.

Thought it’d been long enough to warrant a new teaser, I’m still slowly working away at it when I can. It’s still a little while away, however I’m really looking forward to just getting it finished now. Spent a good while recently going back to all complete zones, smartening them up and really trying to make each one feel unique. There’s very little left to do now in comparison to what’s done.
