Underkeep
Play the final boss: dig a maze, stop the adventurers
by chris lee
Summary
You dig corridors, place monsters and traps, and fold the path back on itself so adventurers die before reaching your boss room. Each wave names the classes coming next, and every adventurer has a weak half — body or mind — so you rebuild between waves and see how long the labyrinth holds.
- 15 monsters, 12 traps, 8 special zones
- Wave preview shows which adventurer classes arrive next
- Everything you build stays after the wave ends
