Tunnels of Doom
Tunnels of Doom is a role-playing video game programmed by Kevin Kenney for the TI-99/4A home computer and published by Texas Instruments on December 31, 1982. It was available in two formats: cartridge with accompanying disk and cartridge with cassette.
Based loosely on the tabletop role-playing game Dungeons & Dragons, it is a dungeon crawl in which players control the fates of 1–4 characters as they navigate a maze of tunnels. Texas Instruments used the game in its marketing, citing it as entertainment software involving "strategy and logic".
Gameplay
The game has four character classes: hero, fighter, rogue, and wizard. The "hero" class is only available in a single character game.Upon encountering an enemy, the game transitions to a separate, graphical, overhead battle screen, where a tactical turn-based combat system is used that allows for movement and positioning. It's possible to listen at doors for sounds of monsters, which can be negotiated with in combat as well.
