I was watching [a video that commented on the use of sound in horror games][1], including *[Perception][2]*, a game where you play a blind woman who has to navigate her way around a house using echolocation to reveal her environment. It reminded me of another PC game I played, maybe ten years ago (around 2010) which used the same gimmick, exception you were playing a naturally blind creature in an alien environment. I think I played the tech demo for it, but never bought the full game. It was a 3D first-person survival/exploration game where you had little to no offensive capability, instead focusing on distracting and avoiding larger predator creatures while not cuing them into your presence by making noise through over-using echolocation. I remember that the echolocation effect involved a circle (several concentric circles?) that emitted from your character's location and then outlined along objects in the environment. I'm not certain if it was monochromatic (reflecting a lack of vision) or colorful (with said color being used to indicate some additional information from the echolocation like maybe different materials). I can see it both ways in my head. [1]: https://www.youtube.com/watch?v=kyNC0deMZEQ [2]: https://en.wikipedia.org/wiki/Perception_(video_game)
