Undying was...an odd game. I got a hold of it a few years ago thanks to my Uncle. Back when I got it I was really into FPS games, and any game written by a known author interested me.
Let me tell you something. Playing this game in the dark when you are 13 can really mess with your head. I remember getting out of one of the paranormal areas to find myself in a closet with a dead body, the blood from said body pooling up on the CEILING. It was...creepy. From that day forward I never played this game in the dark again.
You play a man by the name of Patrick Galloway, who is going to his old War Buddies home to help him with some family matters. When you get there, strange things start happening. Creatures that never should have existed appear, and start to attack the house. Its your duty as a friend of the man who called you here to solve these issues and discover the truth behind the madness.
Overall this game is solid, and creepy as all hell. To this day I cannot play it in the dark...
Stupid closet with blood flowing the wrong way.
