Terminal Velocity

Critics often compared it to Descent and praised its graphics, although some were turned off by what they thought to be the gameplay's lack of depth. Terminal Reality also developed a similar game, Fury3, published that same year by Microsoft. It uses the same game engine and basic game mechanics, but was designed to run natively on the new Windows 95 operating system, leading it to be described as essentially the Windows version of Terminal Velocity.

Terminal Velocity is a combat flight simulator. The player's craft has no inertia, meaning its course can be changed instantly and can fly at low speeds without falling. There are seven different weapons, ranging from guns, blasters and rockets to homing missiles and a rare secret weapon. Additionally, the player's craft possesses powerful afterburners that allow it to move at very high speed, which is useful in order to evade attacks, but sacrifices the ability to return fire temporarily (they can be selected like weapons, and if they are, the fire button will ignite the afterburners). The craft is able to survive some hits, and even some collisions with the terrain, including tunnels. Each of the 27 missions consists of several objectives, e.g. enemies which must be destroyed, tunnel entrances and exits, mere checkpoints, and an extraction point. At the end of each planet is a boss enemy that must be destroyed before either proceeding to the next planet or completing the episode.

The story is set in the year 2704, when the Alliance of Space-Faring Alien Races (ASFAR), of which Earth is a member, suddenly turns against Earth and their fleet ravages the planet, starting a war. The player flies a powerful starfighter, the TV-202, in a series of missions to defeat the enemy. In Episode 3, the player learns that a huge supercomputer known as Xenocidic Initiative (X.I.), located on Proxima Seven, is responsible for the war. Their final mission is to eliminate it. A hidden mission can take place after the main plot only in the CD ROM version where the player must investigate a sudden metamorphosis of an unknown nearby planet and destroy the force that changed the face of the planet. It is revealed here that this force drove a man named Sy Wickens into insanity, and how the X.I. Supercomputer had "accidentally" digitized Sy Wickens' persona.

Terminal Velocity (called "Velocity Brawl" during development) was co-produced by Tom Hall. The main programmer of the game was Mark Randel, the former lead programmer of Microsoft Flight Simulator.

The game has three episodes, the first of which was distributed as shareware. Each episode features three different worlds, making a total of nine levels; the only exception is the final planet of Episode 3, Proxima Seven, which has only two stages. Following the release of the shareware version, publisher 3D Realms was inundated with requests that the game be playable with a mouse, leading the company to include a mouse option in the commercial version of the game. The original floppy disk release was followed by a CD-ROM version. The CD-ROM version added 70 MB of extended pre-rendered 3D cut scenes, a bonus hidden planet, higher image resolution (including more detailed textures) and support for 8-player network multiplay. The Macintosh port was published separately by MacSoft. In June 2015, to celebrate the game's 20th anniversary, the game's original developer and one of the co-founders of Terminal Reality, Mark Randel, released a version for Android and iOS, published by Trebuchet Entertainment. A remastered version, subtitled Boosted Edition, was released on March 14, 2023 for Windows, Nintendo Switch, PlayStation 4 and Xbox One. It adds widescreen support, upscaled graphics and extended draw distance.
