That location is present in the RPG. The world is completely taken over. But it's not their homeworld. They are either created (by David, which is being retconned to it being the Engineers actually, we'll see how long that lasts, at least for this version of the Alien that we know and love) or is ancient and from somewhere far far away (from one of the old Prometheus scripts, being added back into the comics and RPG, but that can change soon as well).
