In Subnautica 2, players can utilize a total of 15 Biomods, with five being particularly beneficial for enhancing gameplay. Dash and Sea Skimmer are essential for improving movement speed, allowing players to navigate the underwater world more efficiently and escape threats. Homing Sense is invaluable for exploration, as it marks powered locations on the HUD, helping players save time. The Camouflage Biomod is crucial for avoiding attacks from dangerous creatures, such as Leviathans, making it easier to scan them without risk. Lastly, Sonic Echo aids in resource collection by highlighting nearby valuable materials like Silver and Titanium. Players can only equip two Biomods simultaneously, so selecting the right combination based on their objectives is vital for success in the game.
