Ahead of the global launch tonight, Microsoft has revealed that soon-to-be Xbox One owners will be able to perform an offline update on their new purchase with a USB flash drive and a PC with an Internet connection, according to the Xbox One support page.

The 'emergeny offline update' as its being called, is on offer to anyone who feels that they may have some troubles come midnight tonight. In order to download the update offline, users will first need to know what OS their system is running, and then download the update to a properly formatted USB with at least 2GB of free space.

Once that has been done, all you need to do is unplug the network cable, power off the console and unplug the power cord. After powering back up — if done correctly — the system will issue two "power-up" tones.

"The first power-up tone will occur approximately 10 seconds after powering up. This indicates that a USB update has been detected. The second power-up tone indicates that the update file has been copied and mounted. This is important, as it confirms you have a compatible Xbox One system update based on your current build. This informs the system which build is currently installed on the console, and whether the update is compatible with that build."

For the full rundown and the file download, head over to the Xbox One support page, and we wish everyone luck as we get closer to the launch of the very first next-gen console in Australia.
