By releasing tech specifications, Sega has made official the promised PC version of Sonic Generations.
Destructoid noted both Direct2Drive and Green man Gaming have entries up for the November release, complete with system requirements.
Although a PC version of the game has been a kind of open secret, Sega hadn't made any official comments regarding it.
Sonic Generations brings together modern Sonic with his 16-bit era counterpart, bending two styles of gameplay across a variety of environments inspired by levels from every Sonic game so far. It's due on 3DS, PC, PlayStation 3 and Xbox 360 next month.
