About this game

Hadal is a turn-based stealth crawl through fog-shrouded deep-sea mazes where you fire a directional sonar pulse to reveal the path ahead before each step. Watch your oxygen drain, grab refills and artifacts, and avoid patrolling predators whose vision cones mean instant death if they spot you. Reach the exit, choose an upgrade, and descend into ever-larger levels as the walls themselves decay around you.
