There is FH 2.0, which drastically expands on the missions found in the original FH. I believe Martin Turner intends to make it for EV Nova in order to take advantage of the engine's capabilities, so you may be in for a bit of a wait. Still, the end result should be more than worth it.
By the way, its possible that Mr. Turner will use the char resource to allow us to play from the perspective of not only Lars, but Jasta Hela, Belan Mordillo, maybe even Alana. Whatever he does with the plug, its certain to be a blockbuster.
