Intro
Setting: You move through a submarine, clearing rooms to escape an underwater base. 1: You must avoid various deep-sea monsters that appear as you pass through rooms. The key is to listen for the sound of an approaching monster and quickly hide in a locker. 2: When a monster approaches, the screen will shake or a distinct grotesque sound will be heard. Hide in a nearby locker immediately. 3: Oxygen is consumed outside the submarine or in specific areas. You must always check the oxygen gauge at the bottom right of the screen.
Supplies Flashlight: The most basic light source. Consumes battery, so constant charging is required. Non-powered Flashlight: Infinite power source that can be self-charged by turning a hand crank without batteries. Blacklight: A lantern that emits purple light. Used to find hidden graffiti, hints, and patterns invisible to the naked eye. Grave Light: A top-tier lantern boasting a very powerful light range and long-lasting battery. Necrobloxicon: An extremely rare grimoire. A top-tier light source item that automatically regenerates energy. First Aid Kit: Instantly restores lost health. Oxygen Tank: Refills the oxygen gauge in areas lacking oxygen, such as flooded zones or outside the submarine. Feritessen: A syringe/potion that significantly increases movement speed for a certain duration when used. Useful for making a quick escape from monsters. Keycard: Absolutely necessary to open locked security doors and proceed to the next room. Battery: Recharges the power of standard flashlights or light source items. Codebreaker: Forcefully hacks and immediately opens locked electronic doors or puzzles. Flash Beacon: Emits a powerful flash to blind or temporarily neutralize specific monsters.
