Sonic Generations has smashed pre-sale records for Sega to become the most pre-ordered game in the franchise's 20-year history.
The platformer – which combines the newer and more retro Sonic the Hedgehog characters – is due out in the UK on November 4th for Xbox 360 and PS3. A 3DS version will arrive later in the month on November 25th.
"Sonic Generations is the ultimate title to cap off Sonic's 20th anniversary and we have put our full support behind it with a number of truly amazing initiatives," said Sega of America's executive VP of sales and marketing Alan Pritchard.
"This year is a milestone for Sonic and we want to make sure this is the best title that Sonic fans, old and new, have been waiting for."
