5-Minute Dungeon is a chaotic, cooperative real-time card game where players have just five minutes to escape a randomly generated dungeon. Communication and teamwork are crucial for survival, as there's no time to devise a carefully thought-out plan—and you never know what dangers await.

Players take on the role of one of ten heroes, each with special cards and abilities. Once the five-minute timer starts, the race is on to defeat all the monsters in the dungeon. To defeat a monster, players must match symbols from their hand with the symbols on the monster's card. At the end of each dungeon, a powerful dungeon boss awaits—and after defeating the first boss, the campaign moves on to the second boss. Each boss, and each randomly generated dungeon, becomes progressively more difficult until players reach the fifth and final boss.
