Fear 2 is a "survival horror" FPS with a great campaign. All the weapons work really well from an assault rifle to a gun that shoots out bolts of lightning and don't make you pissed off. The levels have a nice variety besides the first few which all take place in a hospital. There are also some levels where you get to ride in a giant mecha suit and go on a killing spree. =] The game itself is also a nice length and is not to short. The visuals and effects on here are not really scary, but the developers did an outstanding job on them.
Fear 2 isn't perfect though. The multiplayer is not really fun at all in here. Other multiplayer FPS like Call of Duty, Halo, or Gears of War blow this away, hell even Resistance 2's multiplayer is better!
Bottom Line: This is a great game that should not be missed, especially because it will be buried under Street Fighter IV and Resident Evil 5 early in the year, and totally forgot about at the end.
