• Creatures: Squidsharks (aggressive)
• Hazards: Easy to get lost in the maze-like structure

Purple Vents

Thermally active zone with unique geology and dangerous inhabitants.

Deep Biomes (300-600m)

Crystal Caves

Beautiful but dangerous crystal formations create a maze-like environment.

• Resources: Kyanite, Diamond, Ruby, Quartz
• Creatures: Shadow Leviathans (apex predators)
• Hazards: Crushing depths, extreme predators, maze-like navigation

Fabrictor Caverns

Deep industrial remains with valuable technology to scan.

• Resources: Ion Cubes, advanced technology fragments
• Creatures: Warpers (teleporting threats)
• Hazards: Warpers can teleport you out of your vehicle

Abyssal Depths (600m+)

World Edge / Void

The map boundary drops into an endless abyss.

Navigation Tips

• Beacons are your friend: Place beacons at your base, vehicle, and important locations.
• Follow the terrain: Unique geological features help identify biomes without scanning.
• Listen to audio cues: Different biomes have distinct ambient sounds and creature calls.
• Depth meter: Always watch your depth. Many dangers correlate with specific depth ranges.
• Day/night cycle: Visibility is worse at night. Plan deep expeditions during daylight.
