After a nuclear war broke out years ago in the Radiation City game world, players arrive in the present day and control a plane flying through an area left abandoned for many years. While flying over the area, they witness an unexpected accident. This game's accident tasks players with surviving in a location full of monsters after overcoming substantial damage to their protagonist. During a plane crash, the player finds reserve health items near the site. They must also quickly find an appropriate carrying bag to hold more extra items; the game limits players' initial inventory space. In this post-apocalyptic world, players can find many hidden houses with additional supplies. They can also grab these items and put them in their inventory.

When looking for objects in the environment, players quickly come across many weapons to fend off approaching enemies. It is necessary to use these weapons because they allow players to fight against enemies who want to approach and destroy them. The enemies in this game vary in type and many were exposed to the nucleus as deformed horrors. A quest exists in the game for when players move to other locations. This mission provides direction for the player's movement without knowing what they will find ahead. It also connects to the narrative system of the game and maintains kidney health as part of its requirements. Of course, it also helps players improve the overall game story. After the end of the world players must journey to survive in the post-apocalypse. The story occurs many years after a nuclear explosion that negatively affected the game's environment. After an accident befalls a character's party in the abandoned area, players find a way to stay alive. In order to play the game properly, you must travel through a wide range of locations and collect the necessary resources. Exploring requires finding tools to fight against monsters with grotesque appearances. Additionally, the player should find weapons to protect themselves from dangerous creatures. Through the game's navigational system, players learn they need to go a specific place in order to progress the story.
