Submarine
Every seal matters
Azuralis survives beneath crushing pressure, where every sealed door and every oxygen line matters. What first looks like a routine patrol becomes an investigation into a crew disappearance, an unknown signal from the deep trench, and the question of whether something is using the darkness to get inside. This underwater RPG on iPhone runs 12 quests of claustrophobic tension and deep-sea discovery.
