Not quite as good as other similar games but worth picking up once you are done with the best of these.
Now obviously it doesn't have the great graphics and atmosphere of Bioshock but it does execute both the shooter and psy powers very well.
Frankly, I think it does a better job as a shooter than a game like Psy-Ops but it doesn't handle the psy powers, which tend to really make games like this worthwhile, quite as well. The powers are useful but a little clunkier than Psy-ops but they are still fun to use and add a lot to the game.
It's really worth the money if you find it used at your local shop. Now Xbox needs to get on the stick and make it BC for the 360.
