Monolith successfully regained control of the rights to the F.E.A.R. name, so Project Origin is now F.E.A.R. 2: Project Origin (like it should have been to start with).

"Why not drop the Project Origin name altogether? Well, for one, there has already been quite a bit of branding associated with that name, but more importantly, when Monolith lost the F.E.A.R. name it asked its community for suggestions to replace it. In a contest, Project Origin was chosen, and thus, the name has ties to the F.E.A.R. community."
