Hmmm, interesting how I will explain this....
When I first played FEAR, I LOVED the scares. It was so beautiful and I wished there was more, so I got Extraction Point and Perseus Mandate. I thought Extraction Point was equally good and Perseus only was good once you entered the cloning facility. Then after I got a PS3 I got FEAR again so I would have it in my library. It was not a good port and I had distaste for it.
Then I get Project Origin-said to fix all the problem of the first and ignore the later additions.
Wow.
Project Origin is beautiful. It retains the scares, less scary but more freuquently Alma comes outta nowhere and tries to kill you. Everything has been revamped and looks beautiful. Sure, the textures are a little bland, but the intense blood effects and detailed enviornments will certainly wow you. The frame rates solid, the audio is good, and it beats the crap out of the demo. Multiplayer is a bit lacking but its no-lag connection and the fact people are on it (as opposed to the original) makes this game a must buy!
