Straightout short and bad.
This game is pretty much about a half vamp, half human girl who collects all these bizarre parts of a former demon's body. You play as the vampire named Rayne. You go from swamps to underground caves. The story is overall short, and the combat itself isn't much engaging.
The graphics are mediocre, and the controls are very confusing to get used to. The sound isn't very good but not very bad either. The weapons used and the close-combat aren't all that great.
Overall, this game is pretty much one of the many chosen "bad ones". Unless you are really obsessed with vampires, this game is only suggested as a rental. Nothing more.
