To set various launch options for Brawlhalla, follow the steps for your launcher below:
Steam

Note that:
* All launch options must be preceded with a dash (-)
* If you have multiple launch options, they must be separated by a space ( )
* You can have as many launch options as you need
* Launch options are processed in the order they are stored - for example, if your first launch option disables EAC (-noeac) and a later one enables it (-eac), EAC will be active
* Launch options are automatically saved once you've clicked out of the launch options text box, but -
* You will only see the effects of these launch options after restarting Brawlhalla if Brawlhalla is currently running.
* Not all launch options are supported for all configurations; mileage may vary depending on your platform and operating system.
