Ventilation Area B is a room in the Agon Wastes in Metroid Prime 2: Echoes. It is a network of tunnels embedded into the natural Agon environment outside of the Space Pirate mining facility. Samus can navigate these tunnels with her Morph Ball. The Space Pirates have set up laser beams that appear and disappear at regular intervals, and are damaging on contact. Careful navigation of the tunnels while avoiding damage is required for Samus to get through them.
