For those whos game crashes on the loading start up screen
The game would never start up regardless of what I did ... I updated drivers, re downloaded the demo just in case, restarted pc ... all the basic stuff you'd try out.
If you are running Bit Defender or a different antivirus program, try turning it off. Also apparently some people are getting it working by running it in Windows 8 Compatibility. Right click the game in steam and go to manage. In here you can access the install path and find the exe to change the compatibility.
Best of luck!
