Level 7: Surviving the Abyss of the Infinite Sea

Level 7, also known as “Thalassophobia”, immerses players in a massive, indoor water-filled area with a concrete ceiling above. The primary challenge lies in navigating underwater environments while managing oxygen (in certain versions) and avoiding deadly aquatic entities. This guide provides strategies for waterborne survival, cave navigation, and evading the terrifying Level 7 monsters.

Key Mechanics & Survival Preparations

1. Water & Movement Mechanics

Buoyancy and mobility: Underwater movement is slowed; mastering buoyancy and precise swimming control is essential.
Oxygen management: Some game versions require monitoring breath or oxygen levels. Use surface bubbles or air pockets to replenish oxygen.

2. Essential Gear & Navigation Tools

Lighting: A flashlight or dive headlamp is crucial. Underwater darkness is extreme, and reliable lighting is mandatory.
Boats / Floats (if available): Inflatable rafts or small boats help players traverse open water safely while minimizing exposure.

3. Entity Alert: The Thing on Level 7 (Giant Fish)

Characteristics: A massive, deep-sea-like creature lurking in open water or deep areas.
Deadliness: High speed and enormous size make it a one-hit kill threat. It appears when players linger in exposed areas.
Counter-strategies: Stick close to the bottom or within caves; avoid swimming in open or upper water layers.

Level 7 Progression & Puzzle Steps

Phase 1: Locating the First Dive Point (The Descent)

Entry area: Identify the designated deep water region to initiate the underwater sequence.
Avoidance: Early scripted entity appearances act as warnings; stay alert but calm.

Phase 2: Underwater Cave Navigation (The Cave System)

Finding markers: Look for dim lights, glowing graffiti, or subtle visual cues as guides.
Path selection: Favor narrow bottom paths or rock wall passages; avoid open abyssal areas.
Puzzles: Certain versions require activating 4–6 underwater valves or switches to adjust currents or unlock next-area doors.

Phase 3: Reaching the Exit (The Final Chamber)

Exit indicators: Correct paths lead to an air-filled room, either on the surface or in a dry cave.
Escape: Use ladders or clearly marked doors to progress to Level 8 (Cave Systems).

Advanced Underwater Survival & Navigation Techniques

Team Coordination

Line-of-sight / Ropes: In multiplayer, stay close and mark each other with flashlight beams to avoid separation.
Oxygen rotation (if applicable): Monitor oxygen levels; alternate between team members surfacing for air or replenishment.

Evading the Giant Fish

Stick to the bottom: Move along the floor; the creature patrols upper and mid water layers.
Flare/flash devices: If available, use flares or light grenades to startle the entity temporarily, creating an escape window.

Conclusion

Level 7 challenges players’ thalassophobia, underwater navigation skills, and teamwork. Success depends on staying low, following light cues, and avoiding prolonged exposure in open water. Players who master these techniques will survive the aquatic nightmare and progress to Level 8: Cave Systems.
