I stumbled upon a listing on the GAME website for a Special Edition of The First Templar:

However, with only 16 days until release there are no details about this at all, and they don't even have a pack-shot up.
It also seems to be £5 cheaper than the standard edition, leading me to believe that it doesn't exist - The price for the standard X360 version is £34.99, whereas this Special Edition is only £29.99!
