The line is a narrative game with integrated puzzles.
In the near future, most of the land was flooded, due to the sudden rise of the seas, creating a social collapse.

A few survivors decided to try and take control again, so they organized themselves into small teams, called lines. These lines were planned for three people, a leader, a safety officer and a health worker. Their mission was to find survivors among the remains of the abandoned cities, prepare them and take them to the few areas where the water had not yet reached, to form communities.

At first everything went well, but with time, some lines disappeared without a trace, so a group of explorers was created, to try to recover the supplies of those old lines and try to find out what happened.
