Ubisoft has revealed that the PC version of Driver: San Francisco will require players to be constantly connected to the internet.
The Driver store page on Valve's service lists "3rd-party DRM: Ubisoft's Online Services Platform" in its game details section, and Ubisoft community developer Mathieu Willem confirmed on the official Driver Twitter: "PC version requires permanent internet connection."
Ubisoft first revealed its controversial DRM in January last year, saying it was "justified by the gameplay advantages offered by the system and because most PCs are already connected to the internet". It went on to say the measure "offers protection against piracy, an important business element for Ubisoft and for the PC market in general".
However, it later loosened its policy so that players only needed to be online when booting up PC titles.
