Graphics were very similar to those used in id Software’s Wolfenstein 3D games, with perpendicular walls, and no texture on the floors or ceilings. The object of the game was to free the player’s girlfriend Penelope from the house of the evil Dr. Hamerstein.

Running into trouble in the underground prison.
N3D followed the story of Hugo, from the Hugo Trilogy, a series of graphic adventures consisting of Hugo’s House of Horrors, Whodunit? and Jungle of Doom. Hugo’s girlfriend Penelope has been kidnapped by the evil Dr. Hamerstein for use in heinous experiments. The player must battle through Hamerstein’s bizarre mansion, underground caverns complete with prisons and laboratories, and finally through a twisted alternate dimension of demons and aliens in an attempt to save her.
