The background of the game is that the protagonist encountered an unidentified attack on the way back to the mission. When he woke up, he found himself trapped on a planet and found that people who had experienced the same experience had been trapped here for a long time.
You can explore on the planet, find logs that others have left on the planet, and scan to get data on the production of various items or buildings. There are land and sea on the planet, you can explore underwater, or you can find other civilized buildings on land.
