I just bougfht it for the PC last night and have played about 2 hours worth.
I absolutely love it!! It pays homage to F.E.A.R, Half-Life 2, Bioshock, and Fallout while introducing the TMD (Time Manipulation Device) which is great fun!
I cannot speak for the whole game since I'm not that far into it but I can honeslty say that it's one of my favorites so far!!
