Do you think the game was designed for the player with intent for them to complete the single missions before the campaign? I see completion of the single missions unlocks alot of stuff and was wondering if the campaign was meant to wait till after.
What kind of stuff is unlocked? I haven't played all of the scenarios in Arma or OA. I did unlock all of the stuff in the armory. Is it stuff you can use in the campaign?
The manual says Library Mode is unlocked when you complete all the single missions, which I think is just information. I can't even get through the damn !st mission to destroy the convoy anyway, so it doesn't really matter.
