About Thalassic
Thalassic is a VR underwater horror survival game set on a planet whose population evacuated a few thousand years ago. You travel through its new ocean world in a submarine, guided over the radio by George, your capsule communicator. As you descend, you encounter creatures thought to be extinct and investigate what lies in the depths. Radiation tests are required every 200 meters to check your safety and whether the planet could support human life again.
Life aboard the submarine
You play the entire game inside the submarine, and can only move your lever down. You manage your hunger and vitals during the trip; if they get too low, you die. You can get food by fishing or from the vending machine. George guides you through puzzles, including finding hologram discs and operating parts of the ship.
The ship's rooms
The submarine has four main rooms, each with a role in the expedition:
- Bridge: control the submarine's movement from a semi-circular glass dome with a view of the surrounding environment. George's radio is here, and you can hear him only while in the bridge.
- Research room: use the hologram pad to display radiation levels, fishing and other hologram discs. This is also your living quarters and the room where you spend most of the journey. Its vending machine is your main food source.
- Engine room: house the engine that powers the ship. It can sometimes overheat, so you need to keep an eye on it.
- Ballast tank: control the submarine's buoyancy and allow it to descend.
