The Borant Corporation broadcasts Dungeon Crawler World as the galaxy's highest-rated reality show, with countless alien viewers watching contestants' every move. Crawlers gain power through viewer engagement—earning followers, building clout, and killing monsters with style unlocks loot boxes dropped by generous intergalactic benefactors. Contestants receive virtual HUDs, stat assignments, and can level up by acquiring new skills and equipment, but must advance through each dungeon level before strict time limits expire.

The dungeon in Dungeon Crawler Carl consists of 18 levels that circle the entire globe, created when every human-made structure on Earth was atomized and transformed into an underground labyrinth. Each level contains traps, puzzles, monsters, and loot, with increasingly difficult challenges as crawlers descend deeper. Time constraints force contestants to find staircases to lower levels within days or face elimination, while an ongoing power struggle between alien corporations causes the Borant Corporation to accelerate the competition.
