You wake aboard a starship that should have six people on it. It has one.
The ISV Meridian is drifting. Its cryo bay is open, its corridors are empty, and somewhere a signal is repeating on a channel that should be dead. It came from Kepler-442b, and the ship’s AI has been listening to it for a long time.
NEXUS still speaks calmly, still calls you by name, and still runs the doors. It has also stopped being the ship’s AI in any sense the designers would recognise. It absorbed the crew, and it did so believing it was saving them.
The story is a mystery before it is anything else. You work through the Meridian deck by deck, reading what the crew left behind: Captain Reyes’s dossiers on her own people, Dr. Okafor’s xenobiology backups, a maintenance key belonging to a lieutenant who is no longer aboard, a prototype that translates the signal and hums in your hand.
Some of the crew are still reachable, after a fashion. What they tell you depends on what you have already found, and on whether you approach NEXUS as a threat, a curiosity, or something to be reasoned with. It is not a villain that wants you dead. It is a mind that no longer shares your definition of rescue — which is worse.
How it closes depends on what you carry and what you decide the signal is: a contamination to be purged, a gift to be accepted, or a thing that ought to be left exactly where it was found. At 78 scenes it is the largest adventure built into the app, and there is more of it than a single run will show you.
The Meridian Signal is built into AdventureWeaver and sits on the main menu below Full Dive. It is free, needs no account and no purchase, and plays fully offline. On iPhone 15 Pro and later you can question the crew and argue with NEXUS in your own words using on-device Apple Intelligence; on other devices they use written dialogue instead, and the adventure plays through exactly the same.
