ロストダンジョン

Advanced Dungeons & Dragons: Slayer is a first-person dungeon crawler developed by Lion Entertainment and released for the 3DO in 1994. It is based on the second edition Advanced Dungeons & Dragons ruleset and uses fantasy role-playing mechanics.

Players create or select a character before exploring procedurally generated dungeons. Gameplay focuses on real-time movement, combat, loot collection, and character progression.

Each dungeon ends with a boss encounter, giving the game a repeatable structure built around exploration and survival.
