What's newin version 1.2.0
• Chapter II — The Other Heart. Answer the seam, then follow the second signal north: a station under the ice, a voice on the radio, a companion in the dark and a story that turns on the answer you gave. The first act is yours to play; the rest of the chapter is a one-time unlock. • The second signal. From your first homecoming, the sonar catches one more fragment of a new voice each day. Answer the seam to hear it whole. • A new beginning: the game now opens in the water, swimming for the station's light, and the first dive comes much sooner. • Your crew have stories. Each survivor tells you a little more at supper, one evening at a time. • The last stretch is fairer: shard progress is shown on the station, and a blackout keeps half the shards you carried. • When you answer the seam, keep your station's whole story as a card: your answer, your dives, your crew. • Made for iPad and iPhone Duo — open the fold and the station log sits beside the game like a book. • A home-screen widget line for the second signal, and quiet reminders when it returns. • A fresh coat of paint: sonar that shifts colour with depth, a crew you can see at work, and story lines that stand out. • Now in Japanese.
About this app
Read full description
You wake cold on a research station at the bottom of the sea. The lights are failing, the air is thin, and something in the dark below is singing — three notes, patient as the tide. HORIZON DEEP is a slow-burn deep-sea idle RPG about bringing a drowned station back to life and diving the black water it hangs in. It starts as one instrument on an empty screen and quietly opens into a whole abyss. RECLAIM THE STATION Pump out flooded compartments one by one, install fabricators and galleys and gardens, and wake a crew of named survivors — each with a knack — to run it. The station is a sealed pressure vessel you have to *keep*: the sea keeps trying to get back in. DIVE THE DARK Trace the seafloor on a live sonar scope with your finger — a floaty, drifting swim through currents, wrecks, scalding vents, and roaming predators you can read on the scope and route around, or turn and fight. Your air is your range: every stroke is a breath, and the only thing that comes home is what you carry back through the lock. FOLLOW THE SIGNAL Recover strange relics and study them at the survey lab to unlock what the deep knows. Crawl the flooded interiors of derelict hulks. Chart named places on the shelf. Piece together why the three notes never stop — and choose how to answer them.
