Use one caller, one carry plan, and one rescue owner
Complex Furnishings is listed as co-op, and badges verify rope-trap rescue. That is enough to justify a focused team guide without making up map routes.
Co-op breaks down when everyone talks at once or chases the same furniture. Keep calls short: landmark first, danger second, action third. When a rope trap happens, one player rescues and the rest protect the route instead of stacking on the same spot.
