Lair is a small-box, euro-style, worker placement, base-building game where you are in charge of overseeing the construction of a secret underground base for your nefarious boss Mr White. Points are awarded for building a diverse layout of rooms. Rooms also have special powers. Direct 2 types of workers; low level henchmen to claim a room, and the boss to activate the rooms powers. These powers can help you get more points, or impede others. Points are tracked along an expanding score track that is also the central elevator shaft. Get your score marker to the bottom of the shaft to win.
