Gameplay
Undermountain allowed the player to interact with NPCs, monsters, and the general environment from a first-person perspective. Real-time combat would mix with puzzles to provide a variety of challenges throughout the vast dungeon.
The game was not the first to bring PC role-playing into a 3D environment, having been preceded by several titles such as Bethesda Softworks' Elder Scrolls series and Looking Glass Studios' Ultima Underworld series. It was, however, noted for being the first RPG to use a dedicated 3D engine such as that behind Descent to create a 3D world based on the Advanced Dungeons & Dragons license.
As the back of the box has stated, the game included six different races that could take on single or multi-class professions with a variety of unique abilities such as thieves being able to climb walls. Over fifty different 3D monsters were in the game along with 160 magical items and forty different spells.
