Clank!: Sunken Treasures

Clank!: Sunken Treasures extends the core deck-building crawl with a sharp aquatic twist, layering in partially flooded dungeon maps and oxygen management that elevate both the tension and the tactical calculus. Within the context of modular board-crawlers, this expansion stands out for its ability to force players into riskier, time-sensitive decisions—balancing the lure of deeper treasures against the mounting threat of drowning. The system’s increased difficulty floor and persistent environmental hazards mean that even seasoned Clank! veterans will find their usual routes and routines disrupted. This is a reliable secondary option for groups who have exhausted the base maps, offering consistent mechanical performance and a shelf presence that justifies its continued inclusion after years of managing tables. Physically, Sunken Treasures is a compact addition: the slim box and condensed components make it easy to store, though the new boards will push the lid if you use inserts. Setup remains straightforward, fitting comfortably into a 15-minute prep window, and the 60-minute session time keeps it accessible as a main event for a focused group or a substantial closer for a longer night. The expansion’s footprint is modest, but the added boards and cards do require a bit of table management, especially when swapping maps or explaining the new environmental effects. From a teaching perspective, this is a procedural system—expect a 20-minute rules rundown, with special emphasis on the nuances of flooded caverns and oxygen tracking. The parallel play structure means you can step away after the initial teach, as players will mostly be navigating their own routes and risks. The core skill dividend here is a heightened demand for forward planning and spatial visualization, as players must constantly audit their routes for air pockets and safe exits. The indirect interaction keeps the room focused but not combative, making it a strong fit for groups who enjoy tension without direct conflict.
