If you are a Parasite Eve fan, (I have the first 2 games, book, and movie) you will be disappointed by this game.
Its a okay game, if you take it out of the context of the series, but I started it and wondered what the heck was going on.
It doesn't seem to have much of anything common with Parasite Eve.
And whatever those Reaper things are?
You'll be tearing at your hair and cussing your butt off at them for their near one hit kills.
But as I said, it's an /okay/ game.
