Shadowrun is very underrated. Read to know why.
The gameplay is also pretty nice. Once you've completed the tutorial, you will see that it is very simple, but that it still let you do a lot. The solo mode isn't as bad as gamespot says. Of course there isn't a really big story around it, but multiplayer compensate enough to forget it.
To conclude, if you are a xbox live user, this game is a real must, if not, then a rent should do. The only missing thing I think is that there is no split-screen multiplayer, which left me a bit cold, but the rest is really good.
