I am a big fan of Risen and I have played it many times in PS3 and at my friends place. So I was eagerly waiting for the release of next part as now I have a system at my place, and now I came to know that Risen 2: Dark Waters has released. But, I was shocked to find out that, I won’t be able to buy it in local stores as it is only available on Steam due to some Copy Protection reasons. I want to know what this steam is. How this steam works. From where should I get the DVD and do I need the internet connection to play the game. Can anyone guide me on this please?
