Any Decent A+ Dynamic Campaigns?

I have been playing whole lotta altis but getting repetitive. Anyone know of any other amazing ones?

Check the MANW SP section of the forums: http://forums.bistudio.com/forumdisplay.php?194-Arma-3-MAKE-ARMA-NOT-WAR-CONTEST-SINGLEPLAYER-GAME-MODE

There's some cool stuff apart from WLA like Rydygier's Pilgrimage or Kydoimos' Resist. I don't want to advertise my own project here but of course you're free to try the Alpha, or better the Beta, once it's released. :)

Check out "Hunter Six, special operations unit" (that name might not be quite right but it's in the MANW SP section). I haven't played it yet but it's one of those open world type missions so that sounds good for you.

Benny's Capture The Island or BECTI for short would be my suggestion.

Just be aware that some mods can interfere and make the mission laggy. I can't remember which one I had trouble with. Probably some AI mod.
