Editing Sonic Unleashed (section)

==Downloadable content==
In 2008, when the game was released to public, the game seemed to not have any [[downloadable content]] planned to release for it, evidenced by the back cover of both the [[PlayStation 3]] and [[Xbox 360]] cases that do not mention that the game supports downloadable content (although it was not even corrected later in the best-seller prints).

On 12 March 2009, the first DLC pack was released for the Xbox 360, with "Chun-nan Adventure pack" name on it; the expansion includes four new daytime stages and two new Nighttime stages for the said country. A frame rate patch was also included to fix frame rate issues on areas and levels in the game such as the hub-worlds and Adabat. The package cost $3.13 USD to download for the Xbox 360 and $1.99 USD on the PlayStation 3, while the frame rate patch comes free. On 26 March 2009, an additional expansion was released called the "Spagonia Adventure Pack". Just like the pack before it, it contains four new daytime stages and two new nighttime stages. Later, a "Holoska Adventure Pack" and a "Mazuri Adventure Pack" were released on 9 April 2009 and 30 April 2009 respectively, also containing four daytime stages and two nighttime stages. On 21 May 2009, another DLC Pack was released including extra levels for Apotos and Shamar, including five daytime levels and four nighttime levels between the both of them. On 11 June 2009, yet another DLC pack was released that included extra levels for Empire City, and Adabat, including five daytime levels and four nighttime levels between the both of them, and it was also said to be the last DLC content for ''Sonic Unleashed''. On 2 April 2009 the "Chun-nan Adventure Pack" was released for the PlayStation 3 on the PlayStation Network, with all other DLC from the Xbox 360 Version were released to PSN later on.
