As posted on 1up, they spoke with Dave Matthews, the primary art lead on F.E.A.R. 2: Project Origin. He states that publishers Vivendi and Sierra have “killed off a few fans” of the Fear series in the past couple years.
“We look at Extraction Point and Perseus Mandate as an alternate universe,” he claims. “F.E.A.R. 2 is about Alma, and we wanted to continue the story the way we originally intended.” he says. Basically they made these expansion games, and you shouldn’t hold them to the story that the original F.E.A.R. and F.E.A.R. 2 are built on.
He also says that because the port of F.E.A.R. for the PS3 which was riddled with problems and disease, and all in all a terrible transfer, they are developing F.E.A.R. 2 at the same time for the PC, PS3, and Xbox 360 so everything will be smooth and in order.
