KRAFTON, Inc. today unveiled the Collector Leviathan, a new deep-sea predator in its upcoming survival adventure Subnautica 2, which is being developed by Unknown Worlds. Revealed in the game’s third developer vlog, the Collector Leviathan represents the next step in the franchise’s evolution with a creature that is both visually striking and powered by advanced AI to create tense, dynamic encounters.
Bringing the Collector Leviathan to Life
The latest developer vlog provides a behind-the-scenes look at the making of the Collector Leviathan, from early concept art by Visual Development Lead Cory Strader to insights from the Unknown Worlds development team. This creature was designed to push boundaries of immersion and threat in Subnautica 2.
- Aggressive First Encounter: The Collector Leviathan is the first hostile leviathan players will meet in Subnautica 2.
- Responsive AI: Powered by Unreal Engine 5 behavior trees and stimulus systems, it reacts to light, sound, and player actions in real time.
- Lifelike Movement: Fully simulated tentacle animation creates more natural and unpredictable interactions.
- Immersive Combat Design: A terrifying roar and powerful shockwave attacks amplify the sense of danger.
Antonio Muñoz Gallego, AI designer for the creature, said, “The Collector Leviathan is not just a monster that blindly attacks players. It is an intelligent and highly threatening deep-sea lifeform that actively reacts to player behavior and pursues them.” He added, “Our main goal with our creatures was to make them feel reactive, so the Leviathan is constantly re-evaluating the situation in real time. To achieve that, we use Unreal Engine 5 behavior trees and our AI stimulus system.”
A New Depth of Survival Adventure
Subnautica 2 is set in a mysterious alien ocean filled with strange marine life, diverse ecosystems, and hidden secrets. Players can explore the depths alone or in co-op with up to three friends, tackling survival challenges in a world where beauty and danger coexist.
The Collector Leviathan marks a major step forward in Unknown Worlds’ goal to deliver creatures that feel alive, intelligent, and deeply integrated into the game’s world.
