NecroVision is a first-person shooter that takes gamers across the frantic battlegrounds of World War I and into a dark underworld of vampires, demons and dark magic. Seeking adventure, young American Simon Bukner joins the British army in war-torn Europe of 1916. During a particularly ferocious battle, Bukner and his battalion are pushed into a series of dark trenches where they encounter mysterious phenomenon. As they move through the labyrinth they discover that there is a greater evil hiding underneath the battle-fields of the Great War — an evil that is forcing its way into our world and threatens to wipe out humanity. In the depths of this newly discovered underworld, Bukner must confront the dark forces and fight for the survival of mankind.

Set in 1916 during the First World War, NecroVisioN casts the player as Simon Bukner, a young American recently recruited into the British Army. His war begins on the battlefields of the Somme, where a counterattack against the German lines collapses into carnage under machine gun fire and mustard gas. Separated from his squad, Simon is drawn into a nightmare that reaches far beyond conventional warfare. A rumor has spread through the trenches of a mysterious infection, one that twists stricken men into a zombie-like state, and the horrors soon prove all too real. Alongside German soldiers, Simon finds himself confronting supernatural forces, including the walking dead, hell hounds, and stranger creatures rising from the mud and ruins. As he fights through the shattered trenches, he glimpses signs that something far more sinister is unfolding beneath the ordinary brutality of the war, and begins to suspect a deliberate, malevolent hand at work behind the manifestations tearing through the front.
