The DRM, which now ships with every new PC game made by Ubisoft, requires that gamers have a constant connection to the Internet in order to play their games. The security feature caused a large backlash by users for its inclusion in Ubisoft's Assassin's Creed 2 title, which was released last month.

The hack itself removes the DRM entirely and is being claimed by a consortium known as Skid Row. It requires users to download and install a modified version of the game's executable file to their computers. These modified game files, alongside a crack that can be applied to a retail version of the game, were uploaded to various file-sharing sites late Tuesday evening.

Attached to the "readme" file that comes with the hacked content (which can be found here), Skid Row alerted other hackers that the group's methods were safeguarded against reverse-engineering in order to fend off competing hacking groups and Ubisoft itself.
