Welcome aboard captain, All systems online! you have to pass through the biomes, making sure to avoid the mega leviathan, the Reaper Mega! you navigate with WASD and have to make stops at diffrent biomes for resources, without your trusty atlas getting stuck, a boneshark nibbling on your props, or the reaper catch up to you! Warning, Creature attack!
i based it off the cut content of the Atlas, and in some dev patch notes, they said early in development that they want to add a giant sea monster just to play with people. this is what i imagined. step inside the atlas and go deal with this thing!
