When the Original F.E.A.R. was released, it was praised for its many qualities; from its spectacular A.I., to its horror filled scenes and its the ability to manipulate the environment due its detail to physics. From previews that I’ve read, Project Origin (the spiritual successor to F.E.A.R. – legal issues halt the ability to actually name it F.E.A.R.) will have a much larger focus on the narrative of the main character that the player controlled throughout the first game and the young, tortured girl Alma.
Other than the narrative, the game promises to make the “the best first-person shooter combat ever” – Lead Producer Troy Skinner. They plan to do this; for one at least by “making the destruction happen an inch from the player’s face”, which from personal experience of dealing with the intricacies of immersion, this is a good way to make the player feel as though they are there in the drama and only barely surviving.
From the previewers (www.gamespot.com) descriptions of their hands-on experiences with the game Monolith (the developers of the game) are doing a pretty good job at making the player feel like their placed in such intense situations.
