Steampunk is a pretty cool looking visual design often but quite rarely used in video games so far. There are almost no steampunk elements in any Sonic the Hedgehog games (As far as I know at least) but Glitcher, the artist behind this image was commissioned to do a Steampunk Sonic. The results look awesome or?

Be sure to have a look at the whole gallery of this artist, its worth it!
