Will the nightmare of war ever end? Will your mind ever find peace? In Ad Infinitum, you play as a German soldier haunted by the horrors of the Great War. As your mind drifts between memories of home and the trenches, you strive to break the endless cycle of pain.

You wake up in your bedroom, unchanged from your teenage years, in a ruined and deserted mansion. But then suddenly you find yourself in the depths where the only beings around are some horrific monsters.

Unable to distinguish reality from nightmare, you will immerse yourself in the story of a man facing his trauma and demons.

The unspeakable nightmares come to life in the recesses of your mind. To escape the traps of death and the terrifying creatures, you must understand each monster and solve the puzzles you will find along your way. From blind demons that can hear even the softest of your footsteps to disjointed marionettes that move in the darkness.

The consequences of war are felt far from the front. As you dig into the past that hides the secrets of your family, which was torn apart by the Great War, you will try to remember. Through exploration and solving puzzles among the walls of your home and the barbed wire of No Man's Land, you discover a chapter in the history of a German family destroyed by the war.
