How to launch Day Z through "Play withSix" with Steam launch options?

[lukeman3000 5]

I want to use these launch options:

-nosplash -mod=@dayz -nopause

Perhaps the -mod isn't needed when you use Six, but I would really like -nosplash and -nopause.

Is there a way to do this when playing through Six?

Also, do the majority of players on here use Six, or something else?

You can adjust startup options in Game browser settings section, click the ARMA 2 logo to get there.

noSplash is already used by default

For withSIX support you're best off using: http://getsatisfaction.withsix.com/
