* GameClient.zip
* StaticData.zip
4. In the command prompt window, navigate to "\CoreClient\CoreClientGameTemplate\DotNetTools"
5. Run 'webfileserver --root "<local path to>\CoreClient\GameClient\Build" --port 57470 --enable-cors'
6. Open the project "CoreClientGameTemplate"
7. Go to the top-left menu item "Turbine Tools->Test->Unity Freeze->Test Thrasher"
