If your Settings menu and weapon selection screen are blank OR if you get an entirely black screen: This is a bug with the game that appears when you are forcing anti-aliasing through your graphics card's control panel. Make sure to set anti-aliasing to use "application settings".
For AMD Cards: 1) Right-click on your desktop 2) Click where it says "AMD VISION Engine Control Center" 3) Click on the "Gaming" option 4) Click where it says "3D Application Settings" 5) Look for where it says "Anti-Aliasing Mode" and set it to "Use application settings"
For NVIDIA Cards: 1) Right-click on your desktop 2) Click where it says "NIVIDA Control Panel" 3) Click Manage 3D Settings 4) Click on the Global Settings or for advanced users you can Add ROGame.exe 5) Look for where it says "Antialiasing - Mode" and set it to "Application-controlled"
In some cases, launching the game in windowed mode (by adding "-windowed" without quotations) to the launch options in the Steam properties for the game also helps with this.
