Blackwater

You are nearly blind. It hunts sound.

Pilot a sub through six pitch-black procedural caves using only sonar pings that paint fading echoes on the walls — and on the thing hunting you. Every ping is loud, every burst of engine speed carries, and a creature that tracks sound alone will investigate, then lock on and hunt; silent running is your only way to disappear. Survive a hull breach QTE once, find the exit airlock before your air runs out, and go deeper into faster, mazier water.

Controls: left stick to move, R2/L2 to act. The game freezes the moment your agent needs you.
