During development of the expansion for Duke Nukem 3D, he quit his position at 3D Realms to co-found the company that became Ritual Entertainment.
His chosen pseudonym dates back to his early work on what became Blood starting in September 1994, based on how he signed off e-mails to designer Nick Newhard.
[2] His transfer to the Duke Nukem 3D team in March 1995 was one of the causes of the strain that lead to Blood being published by GT Interactive over 3D Realms.
He created the first suspended platform, aka "void", deathmatch called HIPDM1 or "The Edge of Oblivion" for the Quake add-on pack Scourge of Armagon.
[3] This "islands in space" design of this multiplayer map became a staple in Quake III Arena and many other deathmatch games.
