About

Undulations

Read full description

It's a survival escape game where you just have to escape from a huge tidal wave on an alien planet. This is a survival escape action game where you must survive by avoiding the huge waves that approach you from the start of the game. The story takes place on an exoplanet that has an abundance of water and an atmosphere that humans can adapt to. However, unlike Earth, due to the gravity of the giant red dwarf star and the orbital speed of about 60 minutes, it was a planet where waves of over 3,000 feet (about 900 meters) constantly hit the surface of the planet. The player takes on the role of an investigator who came to investigate the planet, and the goal is to escape from the waves and survive.
