To the surprise of many, Sonic the Hedgehog (2006) has been relisted on the Xbox 360 marketplace. Unfortunately, this means it's only available to download on the Xbox 360. Pure Xbox can confirm this game can be purchased (at least for now) from the Xbox Store.
Sonic the Hedghog (2006) was originally released on the Xbox 360 and PlayStation 3 to commemorate the 15th anniversary of the fastest hedgehog alive and was also a reboot.
It's unknown why exactly it's back on the Xbox Store, but keep in mind it's not backward compatible with the current generation Xbox Series X|S or Xbox One systems - so you'll need access to a 360 to play this one. If we hear any updates, we'll let you know.
