The original Subnautica is often heralded as one of the greatest exploration games of all time, yet Subnautica 2 has the opportunity to deliver an even more fleshed-out world than its predecessor thanks to plans for the game to feature a much more ambitious map size. For it to really achieve that, though, Subnautica 2 is likely going to have to do a few things differently than the first game. While the sequel shouldn't stray too far from the formula that defines the franchise, Subnautica 2 will be taking players to an entirely new planet, and with this new setting comes endless possibilities.
