Last week, the next No Man’s Sky update, The Abyss, was announced, and now the new content is ready to be downloaded. The Abyss revamps underwater exploration in a big way, adding new aquatic plants and animals, sunken wrecks, and a nifty new submarine, the Nautilon. There’s also a new story mission, The Dreams of the Deep, in which you’ll investigate two tales of deep sea tragedy. You can check out a trailer for The Abyss, below.
