This version of PES will require Xbox 360® users to have an HDD (hard disk drive) unit available on their console in order to download the first and fully loaded Patch, including a fantastic range of online modes and functionality, that for technical reasons we couldn't include in the disc.
PES Productions will support non HDD Xbox 360®'s as quickly as possible with an additional patch and would like to apologise for the delay.
*If your Xbox 360® is not connected to the Internet and you intend to play online, you will not be affected by this.
