Got the game through steam (only $40!). After downloading it I didn't have much time to play but I did try a bit of the first mission.
This is not your normal simplified FPS. There's a bit of a learning curve but I think it'll pay off when it comes to the experience of using strategy to complete a mission making it feel much more real which then intensifies the experience of the fight. Also, the game UI was clearly made for the console - with a lot of "Enter" clicks and what I find to be a clumsy radial command prompt for the PC. I'm sure I'll get use to it though.
Really looking forward to playing this with a group of friends.
