The first official teaser trailer for Subnautica 2, which premiered during the October 2024 Xbox Partner Showcase, sent the community into a frenzy of frame-by-frame analysis. While the trailer focused on the stunning new biomes and the revelation of 4-player co-op, eagle-eyed fans discovered a set of flickering coordinates hidden within the holographic display of the new Wakemaker Seaglide.
These secret coordinates are more than just flavor text—they are a direct nod to the real-world inspiration behind the sequel’s most daunting new environment.
The Coordinates Decoded
During a split-second transition at the 0:42 mark of the teaser, a digital readout on the player’s HUD displays the following numbers:
17.3161, -87.5350
Where do they lead?
When plugged into any real-world map, these coordinates lead directly to the Great Blue Hole in Belize.
Located off the coast of Belize in the Lighthouse Reef, the Great Blue Hole is a massive submarine sinkhole that is over 300 meters across and 125 meters deep. For the developers at Unknown Worlds, this is a “meta-hint” at the sequel’s core setting: a world dominated by massive, vertical “Blue Hole” biomes and ancient, crumbling ruins that descend into a dark, pressurized abyss.
Why the Great Blue Hole is Significant
The inclusion of these coordinates isn’t just an Easter Egg; it confirms several community theories regarding the gameplay loop of Subnautica 2:
- Vertical Exploration: Unlike the sprawling horizontal map of the first game, Subnautica 2 emphasizes “The Drop.” Players will navigate deep, circular depressions in the ocean floor that house entirely self-contained ecosystems.
- The “Blue Hole” Theory: Community members on Reddit and Discord have theorized that the player character is a “pioneer” sent to investigate these specific geological anomalies, which act as gateways to the planet’s deepest secrets.
- Real-World Terror: The Great Blue Hole is famous for its lack of oxygen at depth and its eerie, silent stalactites—themes that the “Dive into the Legacy” developer vlog (March 2026) confirmed would be central to the game’s survival-horror vibe.
Other Hidden Details in the Trailer
Beyond the coordinates, the first trailer contained several other “blink-and-you-miss-it” reveals:
- The Tadpole Submarine: A new, highly maneuverable scout vehicle designed for tight vertical spaces.
- Architect/Human Hybrid Tech: The scanner tool now features a holographic display that mirrors the ancient Architect technology from Below Zero, suggesting humans have successfully integrated alien tech.
- The “Void Leviathan”: A brief silhouette of a massive, kraken-like creature seen at the very end of the trailer, lurking in the darkness of a deep sinkhole.
