C&C: Tiberian Dawn

After finishing a GDI mission where you saved a town from being wiped out by the Brotherhood of Nod, a cinematic plays featuring a reporter in front of a scene of destruction, falsely claiming that the aforementioned town was wiped out by GDI forces. It then cuts to a green-screen in a studio, where Kane begins to give orders on the distribution of the propaganda video, before noticing the camera and shooting it.
