"Eternal City" is a game where you control a character that has the ability to use a wide variety of weapons. As the protagonist, you will have the ability to destroy monsters and open a black gate that will allow you to travel between dimensions. However, this ability comes with a price. You will lose your life if you use it.

The game begins in a city where the monsters are attacking and the entire city is covered in a fog. You will need to learn more about this world and the monsters that exist in it. To do this, you will need to explore the city and interact with the people that live there.

Throughout the game, you will encounter various weapons that you can use to destroy the monsters. Each weapon has a different effect and range, so you will need to learn how to use each one of them.

The game is not only about destroying monsters and opening gates. It is also about exploring the different worlds and finding your way in each of them.
