As you slowly regain consciousness, you find yourself lying on the damp ground of a cavernous cave. The air is thick with moisture, and the walls glisten with moisture, casting a surreal blue tint over everything. High above, the cave's entrance reveals a glimpse of a lush jungle, tantalizingly out of reach. Beside you, you spot a flashlight and the unsettling remains of someone who had also fallen into the cave. Their abdomen is grotesquely swollen and appears to be pulsating. Despite the eerie sight, you notice that they have gear that could help you survive in this mysterious environment.
