Not the best FPS but well worth £2.99
Necrovision is a first-person horror shooter, which sees players fighting their way through the bleak trenches of World War One and into the very jaws of Hell. Alan Bukner is an American soldier who joins the Allied Forces but nothing could prepare him for the horrors of the Great War. After his battalion is stranded behind enemy lines, Bukner is trapped in a mysterious trench where all is not as it seems. Dead soldiers are coming back to life with a lust for human flesh, a mad German scientist has created a giant robotic scorpion and an ancient war between vampires and demons is threatening to wipe out humanity. Armed with his powerful Shadow Hand and demonic weapons, Bukner must battle to save himself... and the world!
