Richard Gray, widely recognized in the gaming community as "Levelord," has passed away at the age of 68. His death was announced by Apogee Entertainment, who honored his "legendary work on Duke Nukem 3D" and the significant impact he had on the industry.
Gray began his career in game design by contributing to Duke Nukem 3D in 1996. Following its release, he co-founded Hipnotic Interactive, which was later renamed Ritual Entertainment. At Ritual, Gray worked on a variety of notable titles, including Quake: Scourge of Armagon, Sin, Star Trek: Elite Force 2, and Counter-Strike: Condition Zero.

He was also known for a unique in-game Easter egg in Duke Nukem 3D, the hidden message "You're not supposed to be here," which was only accessible through cheat codes. Gray entered the game industry at a later stage in life, having begun creating Doom levels in his mid-30s. Apogee founder Scott Miller noted that Gray was in his 40s when hired for Duke Nukem 3D, recruited from the active Doom modding scene.
"He then moved to Dallas, and worked from our offices," Miller recalled. "He got along well with everyone and impressed everyone with his dedication and talent. Richard loved to push the engine to its limits and he came up with a lot of fun level design tricks, using portals for example, that our other level designers learned from. Richard was also so helpful to anyone who approached him for help getting into the industry or becoming a better designer. He had a terrific sense of humor, too. For example, in Duke 3D he made this hung jury room. A real legend."
Fellow developers shared tributes to Gray's character and contributions. Frederik Schreiber, CEO of Slipgate Ironworks, described Gray as one of the kindest people in the games industry, highlighting his humility, intelligence, and creativity. Cliff Bleszinski, creator of Gears of War, stated that Gray paved the way for many level and environment designers. John Romero, a co-creator of Doom and Quake, remembered Gray as a great guy, full of life, a gentle soul, and an excellent level designer, adding that his distinctive designs in Duke Nukem 3D's second and third episodes were particularly impactful.
Joe Siegler, who shared the news of Gray's passing, mentioned that Gray had been dealing with cancer for some time. The exact cause of death was not announced.
