Client Launch Parameters

To launch most versions of the game without any launcher you can use the following combination of launch parameters: "-robocopy -nosteam".

Older versions of the game from before BitRaider was removed require the following parameters: "-nobitraider -nosteam".

Some of these parameters can be set automatically by using Bifrost.
