Really great game. I came to know about this game from my colleagues in office. I am not a gamer but it influenced a lot to me to play it again and again. Especially the feature of playing with your office colleagues through LAN is awesome. Though it is not so easy to kill enemies but when I find enemies and kill them is a great feeling and thats why it is great stress buster.
