01The story

The last pilot in the air when the city went dark.

Twenty-two days after an accident at a research station on the mountain, Byzant is sealed behind a quarantine wall. Something that slept for thousands of years at the bottom of the strait has woken up.

Navy pilot Morgan, call sign Raven, is sent to drop a chemical mist on Aurora Station. In the middle of the target, a light on the antenna is blinking: three short, two long. The code he taught his little sister when they were kids.

That night he is shot down. He wakes in the snow with a survival radio, a torn parachute and seven days until the military finishes the job. The mist will kill the colony. It will also kill everyone the colony has touched. Lily included.

02Rime

Light is a language.

The colony isn’t a swarm of monsters. It is one network, like fungus under the sea, and it speaks in light. Learn its rules and you learn how to stay alive.

  1. 01Cold slows themIn the daytime cold the infected are sluggish. At dusk they wake.
  2. 02Silence is lifeSound draws them. A gunshot can call a whole street. Some of them only hunt by ear.
  3. 03The right code calmsFlash the right pattern and they settle. The wrong one sets them off. Strong light stuns.
  4. 04They come homeEach night they walk back to their homes and jobs. At dawn they return to the water.

They’re on the road. They’ve seen you.

Flash the code: three short, two long.

They answer.

The road opens.

03Seven nights

Every dusk, the water really rises.

And every night it climbs higher than the last. Survivors chalk the date of each tide on the walls. On the seventh night it tops the quarantine wall.

Night1/ 7

The water comes back from the strait for the first time. The infected come with it.

04Bestiary

Every one of them was someone.

You can read who they were from what they wear: a tunnel worker’s hard hat, a fisherman’s oilskin, a ferry passenger’s life jacket. Each kind hunts differently, gives a warning before it strikes, and has an answer somewhere in your pack.

    05A prologue and nine chapters

    From the last ferry out at dusk to far beyond the clouds.

    Voiced cinematic scenes, and a cast who remember what you did. Who you trust, who you go back for and what you leave behind decide how the seventh morning ends.

    1. The last evacuation ferry crossing a glowing straitP

      Day 0 · 16:40

      Last Sortie Free

      The last evacuation ferry leaves at five. That night Raven flies over the quarantined city, sees a light blinking in the target, and is shot down.

    2. Ivy flashing a lamp from the station roof over a field of glowing infected1

      Day 1 · First night

      The Light Free

      Wake in the snow. Follow the valley road past the army’s last stand up to Aurora Station, where the light is still blinking. Then survive the first night.

    3. A crashed jet in a snowy city square2

      Day 2

      Wreckage

      Down into Byzant’s steep streets to the square where your jet came down. The battery, the radio and the black box are still in there.

    4. A sealed underground garrison corridor3

      Day 3

      Garrison

      A blast door welded shut since 1957. Six floors down, the soldiers are still in their bunks. They get up when you come close.

    5. A rail cart in a flooded tunnel lit by red lamps4

      Night 3

      The Buried

      A flooded rail tunnel where blind Listeners hunt. Every forty seconds the tide pounds the ceiling, and for a few seconds they can’t hear you.

    6. A half-sunken port with cranes and drones5

      Day 4

      Harbor

      A half-sunken port, drones sweeping it with searchlights, and the old ferry lying on its side. Here, the light that saves you also gives you away.

    7. A radio telescope on a snowy peak above the clouds6

      Day 5

      The Tower

      Climb the giant radio telescope in a storm, with lightning on the poles and a familiar jet in the sky.

    8. Water rising inside the station's silo7

      Aurora Station · Day 6 · 22:40

      The Tide

      The water fills the station from below, fast enough to watch. What you have to carry up takes both hands.

    9. Bombers over the station at sunrise above the clouds8

      Aurora Station · Day 7 · 04:55

      Dawn

      Bombers overhead, the tide at the wall, and a rocket from 1957 on the pad.

    06More than a shooter

    Survive with what you can carry.

    • Fly the last sortie

      Fly, climb a wall of ice, hold a flooding garrison, launch a rocket at dawn. Every chapter plays differently.

    • Scavenge and choose

      Carry what you can, and decide what’s worth the space in your pack.

    • Choices that cost

      Who you trust, who you go back for. The people around you remember.

    • Made for touch

      A floating stick that appears where your thumb lands; push past the ring to sprint. Keyboard and mouse work too.

    • Checkpoints

      Your progress is kept when you have to put the game down.

    • Plays offline

      No account, no connection needed. On a plane, on a train, in a blackout.

    When does it come out, and where?

    Nightide is coming soon to iPhone, iPad and Android. Check back here or on the App Store and Google Play.

    How scary is it? Who is it for?

    It’s rated 13+. Expect blocky (voxel) violence, pixel blood, a heavy horror atmosphere and some mild language. Nothing photorealistic.

    Do I need an internet connection?

    No. The game plays fully offline. Buying or restoring the full story needs a connection.

    Where is my progress saved?

    On your device, at checkpoints. Uninstalling the game deletes it.

    I bought the full story. How do I get it on a new phone?

    Open the unlock screen and tap Restore purchase while signed in to the same App Store or Google Play account.

    Do you collect my data?

    Only anonymous play data (where players get stuck, crashes, device type), never your name or account. In the EEA, the UK, Switzerland, Türkiye and South Korea the game asks first; elsewhere it's on from the start. Turn it off any time in Settings → Play Data. The game works the same either way. Details in the Privacy Policy.

    Something’s broken. Who do I tell?

    Write to melonryou@gmail.com with your device model, the game version and the chapter you were in. More on the Support page.
