Dear all,
We've found an inconsistent bug when we start mission 28 after the cutscene that the mouse cursor is found to be inoperable.
A fix it on the way. However, for those who have played till there, you could restart the game, then go to Single Player > Continue Campaign to continue where you've left off. Nothing will be lost.
Sorry for the inconvenience caused.
Bug will be fixed by V1.04.
Have a Merry Christmas!
