Ludocraft send word that they have opened the shop for Air Buccaneers HD, allowing you to get permanent access to the alpha and all the builds beyond that. They are also following a "benefactor" (ie Kickstarter) model which allows you to contribute more for some additional bonuses and early adopted stuff that won't be obtainable later on by anyone.
There's a new version of the alpha up, too. We'll get an RPS server set up for this next week. Trailer belowdecks!
