MIG-31

It's a bit funny how the corporate world works. In 2005, Sierra and Monolith put out an acclaimed first-person shooter called F.E.A.R. that blended elements of Japanese-style horror with kinetic gunplay. But prior to that, in 2004, Monolith was acquired by Warner Bros. Interactive Entertainment, which meant that things would get complicated for any follow-up. Sierra owned the name F.E.A.R., but Monolith was the company responsible for actually making it. So what happened next was a bit comical. Warner Bros. Interactive Entertainment announced Project Origin, a game that would effectively be the spiritual successor to F.E.A.R., while Sierra would make F.E.A.R. 2 with another developer.
