If you have a gaming rig and you don't have this game then let me be the first to say, shame on you! Seriously this is the game you need to get. To me personally, this game right here is what defines what being a PC gamer is all about. Given that it is still in alpha stage, this right here is phenomenal.
Watch the Trailer here.
