Insert witty hook here
Explore the depths of a deep ice cave system and discover the fate of "The Icarus".

I am super tired and can't think of anything interesting right now, so here is the basic pitch. You are in a submarine delving deeper into a pitch black cave searching for the lost submarine "Icarus. * You can only see what the sonar is making out. * Can you navigate the depths and uncover the secret behind the "Icarus's" disappearance?
