Unsurprisingly, the launch of Black Ops 2 was biggest of 2012 so far hitting the number 1 spot on all platforms.
With 60% of all sales being on the Xbox 360, 38% on the PlayStation 3. Which leaves the heavily pirated PC system with about 1% of the sales.
Even though the Black Ops 2 launch has been a big success, in terms of all time launches it still falls behind the first Black Ops, Modern Warfare 3 and Modern Warfare 2.
