F.E.A.R. 2: Project Origin is a sequel to F.E.A.R. with enhanced graphics and sound, but otherwise not that different.
Gameplay is pretty much the same, the atmosphere is still great and the story continues from where it ended in the first part.
A minus would be that the fights become repetitive and not as much fun, the multiplayer is still lame and you can't save the game when you want to, but have to wait for a checkpoint.
