10 Most Insane Open World Game Enemies You Must Find

The sea is a deeply terrifying place, full of unexpected horrors. Subnautica takes that fear of the deep ocean and brings it to life, with the dreaded Leviathans being the apex predators of this watery world. But, even among them, there is a hierarchy. Remember, there's always a bigger fish!

Sea Dragon Leviathans are a colossal species and are the game's largest aggressive creatures. You don't want to tangle with one as this thing can obliterate you with no questions asked. They have a bite capable of an instant kill, fire breath, and plenty more hunting power at their disposal.

Oh, and if this creature wasn't already scary enough for you, guess what it eats? It's Reaper Leviathans. Yes, one of the scariest creatures in the game is what these colossal sea creatures like to chow down on.

There are only three of them in the game, but they're worth seeking out. Encountering one of these beasts is indeed something you'll struggle to survive. Still, it's an enemy you've got to see just for the sheer spectacle.
