A bargain bin treasure.
You play the role of a scientist on a counter-terror team who is inflitrating a lab. You end up getting captured and held for an experiment where your soul is ripped from your body, you then become a 'geist'. You uncover a plot...well, I won't spoil any of that. But your goal is to get your body back and put an end the the evil that is occuring. To do this, you have to travel throughout the expansive complex, going from ghost form to possessing people or things as necessary. In order to complete the game, you have to possess several different people, animals, and objects, everything from a bowl of dog food to a heavily armed mercenary. In order to possess something living, you have to "scare" it first. You do this by possessing objects in the room, often requiring a chain of possessions to reach your goal. For example, you may have to possess a light so you can shatter it & scare a parrot, so you can possess it and threaten a human with it and then possess that person.
The graphics are excellent. The characters are detailed nicely, and the environment is diverse, from a laboratory setting to an abandoned building setting, all of which give you a good feeling of what you're supposed to be experiencing.
The sound is likewise excellently done. The voice acting is professional, and the music fits with the feeling of the game beautifully.
The gameplay is good. A lot of people put down the FPS gameplay. And really, it's not as good as some other FPS's, but it's not bad, and there's just so much more to this game than running & gunning. Occassionally a boss battle will be a little tedious, but even that is very easy to overlook considering how well this game was done.
If you have a Gamecube, put this on your list. Considering how well done this game is, how easy it is to find, and how cheap it is, there's really no excuse not to play it.
