Fans have done what Sega won't - clever-clogs modders have released a version of Sonic Unleashed for PC.
The free download works as a total conversion mod for Sonic Generations. You'll need a Steam copy of that game for it to work, and the 2.34GB download file from ModDB.
The new version includes support for unlimited resolutions, new higher-quality textures and 60 FPS gameplay.
Eight modern sonic stages have been "re-adapted" from Sonic Unleashed with a number of improvements. There are "no mandatory RPG elements, no medal collection, no Werehog", the creators have promised.
Modders have even gone through and fixed a number of bugs and glitches in the game.
Crank up the gameplay video below to 1080p full-screen mode and see how it looks.
