Subnautica 2 screenshots: exploration, vehicles & co-op
Three different angles on what the game actually looks like underwater.
Subnautica 2 items & resources to know first
Eight starter and early-route materials that drive the first powered base, Scanner progress, Habitat Builder chain, the Hotfix 2 mineral rebalance, and the Hotfix 3 Interior Wall cost change. Each links to the full resource or base-building guide.
Titanium
Starter construction material behind Survival Multitool, Scanner prep, and the Habitat Builder chain.
Glass
Quartz-to-Glass crafted material that gates first-base windows, Scanner rooms, and Moonpool prep.
Copper
Drives Basic Battery, Copper Wire, Scanner, and early base power planning during the first hour.
Quartz
Shallow starter mineral that feeds Glass and supports Scanner / first-base material prep.
Silver
More early-region areas after Hotfix 2; tied to Air Tank planning and Rebreather depth progression.
Troilite
Late-region material after Hotfix 2; feeds Metal Farm, Mangalloy, and Alien Power Plant route context.
Interior Wall
Base-building cost changed in Hotfix 3: Interior Walls now cost one quarter of the previous price.
Atacamite
East-northeast Alien Ruins lead under ~250 m, used for repair and upgrade route planning.
Subnautica 2 creatures & leviathans tracked here
Eight creature trackers covering apex leviathans, mid-route hazards, and ambient fauna. Threat tier, biome context, and patch-aware notes live on each detail page.
Void Leviathan
Open-water apex tracker for the deepest routes; evasion-first planning, not combat.
Collector Leviathan
Sparse Plains apex leviathan flagged in dev vlogs; route, aggro, and audio cues stay version-sensitive.
Deepwing Brooder
Deep-route leviathan tracker; lure, line-of-sight, and aggro behavior under active patching.
Hammerhead
Low-risk diver scan, but Tadpole state now matters: unpiloted vehicles are no longer attacked.
Marrowbreach
Predator tracker with higher damage and less frequent attacks after the latest tuning pass.
Nibblershark
Predator tuning changed perception, movement, circling time, Multitool sensitivity, and damage.
Opal Prowler
Mid-route stalker tracker with patch-aware notes on aggro range and pickup planning.
Waterslug
Smaller fauna tracker for scan, lure, and ecosystem context around starter routes.
