@punksterdaddy: I haven't experienced any of the bugs on PC but the game was badly optimized and the framerate was low even on minimum details. There's no excuse for Telltale if Life Is Strange, a much better looking and more detailed game on Unreal engine, runs much smoother than this mess.
The movie District 9 has a very similar atmosphere and visuals to Half-Life 2. I've heard the story of Half-Life was inspired by Stephen King's The Mist.
