Descent to Undermountain (also known simply as Undermountain) is a role-playing game created and distributed by Interplay in 1997. It was developed by Chris Avellone, Scott Bennie, John Deiley, Robert Holloway, Steve Perrin.
The game partially derives its title from the use of the Descent 3D graphical engine. Undermountain allowed the player to interact with NPCs, monsters, and the general environment from a first-person perspective. The quest took place within the environs of the infamous super-dungeon of the Undermountain. Real-time combat would mix with puzzles to provide a variety of challenges throughout the vast dungeon.
While the game had a widely negative response, it was also historic as it marked Interplay's first RPG with Interplay's Dungeons & Dragons License.
