I own the Steam version and have completed it. It's one of those games that you wish wouldn't end. It's that good. It has to be one of the very best games I've ever played and top of my list of the best in the last decade. Not brutally hard just right. Everything about it from the story line all the way down to the music is incredible. Get it. You'll see quickly what I'm writing about. If you like post apocalyptic storylines you're going to enjoy every moment of it. I just wish they would do a sequel like they did with the movies.
I've played this on Steam with a couple hundred hours into it and it's a blast. You have to go through the built in tutorials if you want to be successful at it. With the ability to set the difficulty helps you learn without having the game pound you to the keyboard without rage quitting. If you enjoy dark (dark and dismal settings) along with cyberpunk post apocalyptic games, along with being a hard fan of FPS genre? You'll do just fine with this title. I sure with they would consider doing a sequel to this.
