Abyssal

In a post-apocalyptic Earth submerged in water, society is attempting to recover from collapse by recovering artifacts from days of yore. You play as Valor, a scout well-versed in navigation of the depths, who has convinced an acquaintance, Quinn, a skilled diver interested in undiscovered riches, to join you in exploring an unexplored region of the abyss. Guide them safely through the dark using various sensors, converse with your sole companion, and find bits of the past along the way.
