I have a used copy of Fracture, it's a cool game selling it for $200 or best offer

The hook of manipulating terrain to your advantage is used a lot in the game, but it is used in a way that it rarely feels out of place. The game length is good, and the enemy AI, while not the best ever seen, is challenging enough to squeeze a good experience out of it. Graphics and sound are above average, and controls are very well done. If you casually enjoy a shooter, you'll try to squeeze every minute of your rental with this one. If you love shooters, make some space in your library for title.
Score: 8.5/10"
