A downloadable game


In the unfathomable depths of the ocean, an enigma awaits to be unraveled. The story of Peral and the Peral Submarine is a mystery hidden beneath layers of history and legend. In a world where time and space intertwine in the shadows, I invite you to take a journey back in time into the dark secrets of naval engineering.

What drove Peral to plunge into the darkest and most dangerous depths of the Mediterranean Sea? What secrets await in the bowels of his invention? As you dive into this world of intrigue, you must unravel the riddles of the Peral Submarine and discover its impact on the course of naval history. Are you ready to face the challenges of the deep and uncover the secrets that lie hidden beneath the waves? Your adventure has just begun.

The Game

The game begins with an underwater sequence where the story of Isaac Peral is summarized. The environment is dark and mysterious, only illuminated by the lights of the submarine.

Throughout the levels, we must collect valuable items to advance and survive:

Map: The map of the underwater labyrinth is separated into different parts across the screens. You will have to collect the map pieces in order to advance in the correct screen order. With them, you will be able to navigate with confidence in the mysterious underwater world.

Energy: The vital source of your submarine. Energy is essential to maintain all operational functions, from propulsion to defense systems. Manage your energy carefully, as every action you take will consume a portion of it - be sure to maintain a balance between exploration and survival!

Oxygen: In the deep ocean, oxygen is scarce and precious. This critical resource determines how long you can spend at depth before you must return to the surface. Monitor your oxygen supply constantly and plan your dives shrewdly to avoid running out of air at the most crucial times.

Torpedoes: Equipped on your submarine, torpedoes are your main line of defense and attack. These advanced projectiles allow you to deal with underwater threats. Use your torpedoes with precision, as their number is limited, and each one must count in your fight for survival in the deep.


To control the submarine and move around the environment, we will use the classic Amstrad controls  or Joystick.

For the best gaming experience, it is recommended to play on a real AmstradCPC(it's magic). But if you don't have one, we recommend using RetroVirtualMachine or WinApe to ensure it works.

He puesto todo mi corazón y empeño en realizar este juego. He dado todo lo que se y he aprendido por el camino. Y quiero dedicarlo a  mi Raquel.

Nice video!

Nice project page which is very complete (narrative, presentation, controls, game screens...). I like the loading screen, the video with the english and spanish subtitles is a real plus for the non spanish CPC users. The making-off is also a nice plus. Waiting for the .DSK but take your time.


Thanks for your comment. CDT  and DSK are ready now.
