Possible DLC (Planet Extension)

TheGreatFork

I think that maybe 4-6 months after the game is released and the "buzz" about the game has died down people will most definitely want more so my proposition is that you make a sort of dlc (free or payed idk) that extends the planet and adds new Fauna/Flora/Terrain I know that the devs are considering an ice biome so that could definitely be implemented. But anyways I was thinking that there could possibly be some sort of extension to the story line where you try to save the planet from the cure not just yourself so maybe you return with new equipment and find more precursor tech in a new area of the planet. You have to use new vehicles and new ores to progress deeper and further away than before to achieve this goal and it could possibly set in the depths of the ocean instead of staying in the shallow areas because although you go very deep in the game there's not much truly open ocean that you can explore and this could make way for the even larger beasts of the sea (possibly larger than leviathan class.) And some sort of trench like areas similar to our planets Marianas trench may be a good idea if you wanted to add some creepy bioluminescent creatures like angler fish (not that there isn't tons of bioluminescence already.)

Part of the victory condition in the game is to dive down and release the young Sea Emperors, which produce the cure to the Carar, so that they can distribute it in the sea and get rid of the disease
