How to craft improved fins in Subnautica 2
In Subnautica 2, improved fins represent one of the most valuable early-game upgrades available to players. These enhanced fins significantly increase swimming speed, enabling faster exploration of the ocean environment, quicker resource collection, and improved survival chances when encountering hostile aquatic creatures. Given these practical benefits, unlocking the improved fins blueprint should be a priority for new players.
To craft improved fins in Subnautica 2, players must first locate and scan three improved fin blueprints scattered throughout the game world. One confirmed location is within the Alien Ruins situated far to the east of the starting Lifepod. After scanning these locations, players will have the blueprint necessary to craft their own improved fins, provided they gather the required ingredients.
The guide recommends enabling all landmark signals in the character menu before attempting to locate these blueprints, as this streamlines the discovery process and reduces exploration time. Improved fins exemplify Subnautica 2’s progression system, where early-game upgrades provide meaningful quality-of-life improvements that enhance both exploration efficiency and survival capability.
