VideoGamer's Xbox 360 review says:
"F.E.A.R. Files is a highly enjoyable package, but the games do show their heritage. Both expansions are based on an engine that we first saw over two years ago and games have moved on. For some thrilling and often scary gameplay look no further, especially if you're a fan of the first game, but gamers who have gorged on Call of Duty 4, BioShock and Halo 3 might find Sierra's latest a little dated."
