Terminal Reality was a video game development and production company based in Lewisville, Texas. Founded in October 1994 by ex-Microsoft employee Mark Randel and former Mallard Software general manager Brett Combs, Terminal Reality developed a variety of games including racing games (such as 4x4 EVO 2), 3D action games (such as BloodRayne), and more.

Mark Randel began programming commercial software at age 15, but it was not until 1991 that Mark entered the computer game industry when he teamed with game programmer Bruce Artwick to write add-on products for the just released Microsoft Flight Simulator 4.0. This led to Mark becoming the co-designer and lead programmer for Flight Simulator 5.0 and designing the next generation flight technology standard. This technology is still in use today by Microsoft in various Flight Simulator releases.

After leaving the Bruce Artwick Organization in mid-1994, Mark and Brett founded Terminal Reality in October 1994, which required Mark leave Chicago where he had just finished up on his BSE and MS in electrical engineering from University of Illinois. The goal of Terminal Reality was to exploit texture mapped 3D game engines, with only $1000, and working out of Brett Combs' home. During that time they were developing their first release, Terminal Velocity, and pulled together $120,000, received advances on the game and were basically able to avoid giving up ownership and primary decision rights to venture capitalists. After that first year the company generated $1.2 Million and nearly doubled it the second year with $2.1 Million.

Terminal Reality's first game, Terminal Velocity, was a 3-D air combat game, Brett Combs pitched to Garland-based publisher 3D Realms. 3D Realms was the new division started by the popular Apogee Software known for its arcade style action shooters and titles such as Wolfenstein 3D. Scott Miller was intrigued by Randel's technology and Combs' management. Scott later said in a Dallas Business Journal report that "They had the backgrounds and track records with proven experience to pull off the game they were pitching to us."

Terminal Reality went on, after the success of Terminal Velocity with 3D Realms, to publish titles with Microsoft such as Fury3, Hellbender, Monster Truck Madness, CART Precision Racing and Monster Truck Madness 2. By January 1998, Terminal Reality became an equity partner and founding developer of Gathering of Developers, a Dallas, Texas based publisher in which Brett Combs sits on the Board of Directors.

In December 2013, Terminal Reality closed down and liquidated its office outside Dallas, TX.

Infernal Engine

In addition to game development, Terminal Reality is also the creator of the Infernal Engine: a cross-platform, full-featured foundation for building video games that the company licenses to other developers and publishers. The Infernal Engine is a unified system, providing rendering, physics, sound, AI, and metrics.

A key component to the Infernal Engine is the VELOCITY Physics Engine: a physics simulator that offers an advanced collision system, dynamic destruction for scenery and environmental objects, accurate vehicle driving dynamics, real human body physics with anatomical joint constraints and simulated muscles/tendons, hair and cloth simulation for actors.

Photex engine

The Photex (Photo-texture) engine was the first photorealistic game engine created by Terminal Reality, developed from the Monster Truck Madness engine. The first game built on this technology was CART Precision Racing, and the final game was Fly! II, which used Photex3. Monster Truck Madness 2 was heavily promoted by Microsoft (its producer) for using the Photex2 engine, which, at the time of its release, was a cutting-edge rendering engine. Most of its games used the Terrain geometry engine. This engine was known for its very fast rendering in low-end pcs, photorealistic images and true color textures.

The Photex2 game engine was composed of two components: the Photex2 rendering engine and the Terrain5 geometry engine.

Nocturne engine

Previously named "Demon engine", it's the rendering engine used in Nocturne and the Blair Witch video game series.

KAGE engine

Developed by the now former TRI employee Paul Nettle, originally written using software rendering, but later adapted to use the OpenGL API.

EVO engine

Based on MTM2 Photex2 engine, it is the game engine used in 4x4 Evolution and 4x4 EVO 2.
