If you experience poor framerate, the fix is here

F.E.A.R. is timeless classic that combines dull world, full of mundane office spaces and warehouses (designers' idea was definitely to try recreate real world with, at the time, improved rendering fidelity to immerse player into the game world and its story better + make supernatural events and surreal secret laboratories stand out all the more, but ended up with world looking colourless, forcing textures to have a rather restrained palette) with great movie action soundtrack and absolutely unparalleled enemy behavior.
The levels might look boring, the horror elements might not work for some players, but what Monolith good at, is all there (well-written, engaging dialogs, sound design with psychotic attention to little details, guns that are nice to use all the way through, eye-pleasing visual effects at the time of release), but your main course is confrontation with enemies that validate your every move, all up to knocking off a coffee mug from table, and try to bring your àss down as a team.
And, without a doubt, FEAR has the most badass explosive barrels in entire history of first person shooters.
F.E.A.R. Extraction Point, however, is a third-party developer expansion that is not very good and missing all the fine-tuning of the original game (dialogs are bland and full of nothing, but constant moping, the audiologs are unimaginative and don't add anything of interest to story narrative, ambient sound design is practically non-existent or full of errors, when you can hear server buzzing near janitor's closet / electric panel, the score is popping in out of nowhere and fade away just as obnoxiously, often leaving you in complete silence). The only redeeming factor is well-directed gruesome death of one of your teammates that properly horrifies you.
F.E.A.R. Perseus Mandate is second expansion from same dev team, where they mixed up a formula, adding several unique looking levels, new enemy flavors, and finally stopped taking the story too seriously and actually added more effort into NPC dialogs, though it ended up sounding forced and not as unconstrained/natural as in original, but still - overall better attempt than utterly bad fanfic-tier writing of previous expansion. It has its moments (like, the most notable improvement compared to original is that setpiece with a massive robot stalking you in building, on a floor right above you, when you can hear their every step and are nerviously waiting for it to break the floor under its own weight)
Try out the main game, feel free to avoid the expansions as they add nothing of value to your experience and, for seasoned players, just make you want to replay the original one more time.
