The Line
No monsters. The cave is the threat.
A cave-diving game for iPhone, iPad and Mac. Follow a single guideline through six flooded cave systems, count your gas, and find out what happened to Nadia Vell.
STN 01 The story
You are the diver who goes in after her. Six cave systems, six people on the surface waiting for answers, and one woman's logbook leading you deeper.
STN 02 How you stay alive
No jump scares. Zero visibility, tight restrictions, a racing heart that burns your gas, and a lamp that can fail. Every dive ends with an accident analysis that tells you exactly which rule you broke.
A single guideline is the only way home. Lay your own from a reel, tie it off on the rock, and clip arrows that point to the exit. Lose it, and you are guessing in the dark.
Breathe a third of your gas going in, a third coming out, and keep a third for when it all goes wrong. Because sooner or later, it does.
Hold the line. Move slow.
STN 03 The campaign
Each system has its own story and its own way of trying to keep you. They open one after another.
A jungle cenote with rooms big enough to lose a house in. Nadia Vell went in alone. This is where you learn everything.
Mud and sumps under farmland that floods when it rains. In 1962 two brothers crawled in; only Josef came out. He wants the cave surveyed end to end.
An alpine expedition, sump after sump into the mountain. Bruno Falk turned at Sump Two in 1998. He would like to know what is past the last one.
Down through the halocline and a maze. Offerings wait on the floor for a diver who will bring them up gently.
A black-water spring whose current never stops. A town drinks from it , a quarry wants the hill above it, and two lost loggers could settle it.
A tea-coloured spring where a diver's line from 1979 still waits. Where Nadia's story ends.
STN 04 Off the line
Tie in a reel and swim into the dark. Every find has a story, and it is only yours if you get it out.
95 finds
left in the dark, each with its own history.
Lost slates with treasure maps
, sketched by divers who never came back for what they saw.
Survey stations
to reach and log, so the people above get the map they need.
STN 05 Every day
The same cave for every diver in the world, for one day. Dive it once for a score, then compare on the Game Center leaderboard.
ONE CAVE · ONE DAY · EVERY DIVER
One cave all week, with one special rule. Your best run swims beside you as a faint ghost, so the only diver to beat is you.
ONE RULE · ONE WEEK · YOUR GHOST
