It will come as a surprise to some, and as the logical evolution to others ahead of the release of Windows 8 later this year. Activision has confirmed that Call of Duty: Black Ops 2 will not support Windows XP.
The second most popular Windows OS hasn't been favoured by developers for a while, but has still been supported in some capacity by many games.
"Since we upgraded the engine to use DirectX11, Windows XP is no longer supported. It requires Windows Vista or later," said Activision in a statement.
It becomes the first game in the series not to support XP.
