About this game
A sci-fi survival-horror game set on an alien planet. Descend into the dark, scan your surroundings, gather evidence, return to base, upgrade your equipment, and head deeper.
You are not alone in these caves... Use your handheld SONAR device to visualize what lies ahead and navigate where your eyes cannot.
Wishlist SONAR to keep it on your radar.
Studying means getting close. Photograph unknown species, record their sounds, and collect physical samples. All without becoming part of the evidence yourself.
Experiment with different frequencies to interact with creatures and mechanisms throughout the caves. Learning how each one responds may be required for your survival.
SONAR is being developed by a solo developer. Thank you for taking the time to explore this page, your interest genuinely means a lot to me.
