The Descent series combines flight simulation with fast-paced 3D shooter elements, placing players directly into the cockpit to pilot a spacecraft through complex environments from a first-person perspective while blasting hostile robots. Additionally, various multiplayer modes are fully supported.

Operating as a "Material Defender" (call sign "Vertigo-1"), the player pilots the compact Pyro-GX spacecraft, fighting their way through dark PTMC mines scattered across distant planets. The enemies are mining robots that have been infected by an unknown computer virus and now react with extreme hostility. The primary objective is to locate and destroy each mine's reactor core, then successfully navigate the escape tunnel before the entire facility detonates. Along the journey, various powerful weapons and equipment upgrades can be collected, while engaging in intense combat against diverse robotic threats. To reach the central reactor, players must first secure the distinct security keys for the blue, yellow, and red sectors.

Released in 1995, the original Descent was the very first computer game to feature a completely unrestricted 3D mine labyrinth, offering full freedom of movement for the player-controlled craft across three axes and six distinct directions (6DoF).

One year later, Descent II followed (released in North America as Descent Maximum), introducing 30 brand-new levels. Fresh gameplay features included energy force fields, as well as destructible switches and lights. The game also added powerful headlights, a helpful companion drone known as the Guide Bot, and of course a variety of new weapons and challenging opponents.

In 1999, Descent³ was launched, continuing the storyline of Descent II. However, this sequel arrived as a highly optimized Windows game utilizing state-of-the-art technology, graphics, and sound design for its time. It brought new weapons, fresh enemies, innovative mission objectives, and 3 distinct ships to choose from. The enhanced Guide Bot, which now featured its own unique powerups, could be carried inside the ship and deployed whenever needed. Furthermore, players were no longer confined solely to subterranean mining facilities.

The development of the planned sequel, 'Descent 4', was officially canceled in 2001.
