In addition, the blog post lists "Steam account required for game activation and installation.

Chris Kline also listed some DirectX 11 features included in the game: " dynamic shadows, diffusion depth of field, high definition ambient occlusion and optimized antialiasing."

The original post also discussed controls (including support for console controllers), multi-monitor support, and Steam Big Picture Mode support, and is well worth a read.
