Staff from TFW2005 site were apparently invited to Highmoon's studios in San Diego, after the SDCC was over, to have a run through the upcoming FOC game.
They've posted up a heap of info and images, which gives us a clearer picture of what to expect from the game, when it comes out next month.

Also of note, is that there will be a demo released some time before the game for people to download and try.
