It seems pretty clear to me that "ludicrous hot air balloon battles with flame-cannons and grappling-hook boarding actions" needs no exposition or back-story, but Air Buccaneers has a rather amusing one anyway. Finnish developers Ludocraft send word that their story trailer (and presumably new game intro) has appeared, and you can watch that below. It's time to coincide with a Christmas sale over the Steams, where the game is a threesomely 33% off. I'm not saying you should buy it, but you should play it. And if you buy it, that will help with that.
