After i download how do I install/play

sorry guys i'm fairly new to the forums and very new to ArmA2. Got it 2 days ago. After I download a new mission, what are the steps i take to extracting/installing and accessing it as a playable mission in ArmA2? Thanks.

U have to extract the pbo file to your ArmA2\MPMissions or ArmA2\Missions or ArmA2\Campaigns folders depending of the type of mission (Multiplayer, Singleplayer or Campaign) and then start your game and you should find them there. For multiplayer u have to create your own server ingame to be able to see them. For SP u find them where you find the original ones.

If you download them from armaholic in the page info there is an installation section with the info.

thanks!

As Big said, just put it into the Missions folder under ARMA2! (or campaign, although for me it was Missions).

Then start your game up normally and go to Scenarios and it will be listed there! Pretty easy once you learn bud (;
