Well-organized and detailed longform (for most FIST content) supplement including a mission, cool experimental items for players to collect, unique monsters to confront, and themed TRAITS for players to acquire.
I have always found deep sea adventures to be naturally intense scenarios, much like deep space, because the environment itself is inherently deadly. With this mission, players have little room, relatively speaking, to flee given the limited number of rooms and their inability to exit the station until they find the escape pod. This intensity is baked into the scenario from the very beginning, as the characters must teleport into the mission without knowing if/how they’ll be able to leave. Additionally, the scenario is cleverly designed to ratchet up the tension and the threat by scaling creatures up as the players complete stages of the mission.
