Dungeon Crawl Stone Soup is a free, open-source roguelike game where players explore randomly generated dungeons filled with monsters, treasures, and traps. Players choose from various character races and classes, each with unique abilities, and must navigate through increasingly challenging levels while managing resources like health and magic. The game features permadeath, meaning that when a character dies, they cannot be revived, adding to the challenge. Players can find numerous items, spells, and skills to enhance their abilities, making each playthrough unique. The goal is to reach the bottom of the dungeon and defeat the Ancient Lich known as the Orb of Zot.
