As if to emphasize the whole point of Early Access, we're excited to announce that an additional area will be available WAY ahead of schedule, i.e. barely a week after the game goes on sale.
We're as surprised as you are.
Now, don't get too excited for what you'd call "frequent" updates, because the one after this is a massive undertaking. That said, it's just as deep in progress as the one in this announcement, so that could well show up earlier than expected, too.
Keep an eye out for updates, and keep on paddling. It's good for your forearms.
