HelpHelp With Wasteland

So how do i launch wateland so it doesnt launch with steam so it doesnt replace my cd key. I also can use the server browser because nothing pops up anymore, if tryed everything too

Go to your steam directory and launch directly arma2oa.exe

Wasteland is a mission style play, so it's not actually a mod. Put wasteland in the mission field when searching for servers

Voila.
