A Dungeon Crawler has the player navigate a labyrinthine environment, such as a dungeon, while battling various monsters, disabling or avoiding traps, and looting any treasure they find. Dungeon crawlers are usually party based and typically feature a first person view window. They have traditionally lacked meaningful plot or logical consistency despite often being paired with the RPG or roguelike genre. Endless procedurally generated dungeon terrain and randomly placed monsters and treasures are common. The 1980s may be seen as the "golden era" due to the simplistic graphic style and the need for repetitive tiles or similar-looking graphics. Some distinguish "dungeon crawlers" from rogue-likes and RPGs with stories and character-interaction, while others use the term to describe any game which features ample amounts of dungeon exploration.
