Renegade Kid has unveiled a new plan for Moon Chronicles, as more is on the way next month. On February 5, episodes 2, 3, and 4 will drop for $4.50 apiece. Or, if you're in a more carefree mode of operation, $9 for the lot.
Since the first episode already exists, the rest is basically an add-on for the previous package. Europe is still MIA in terms of a release of any kind.
