I loved the first FEAR and I can say I enjoyed the second FEAR. The story continues with you trying to bring down Alma and finding out what really was behind the story of Alma and the experiments they forced her to undertake. They wanted to use telepathy in order to control soldiers. The army wanted to contain Alma and use her experimenting on her to create the ultimate soldier: Replica, a super-soldier. The gameplay is the classical FPS one: get a weapon and shoot them all. The atmosphere is at times a horror-survival one (especially in the hospital and kindergarten) and what ensues is pure FPS. There are some bosses and the firefights are really lively.
If you love FPS just do it.
