Path of Roots is a room in the Torvus Bog area of Metroid Prime 2: Echoes. When first entered, Samus is underwater, and her path is obstructed by a strange cage-like structure. There is a tiny space underneath it that the Morph Ball can fit through. Samus then climbs some "stairs" out of the submerged part of the room. From here, she can use a Grapple Point later on to collect a Missile Expansion, scan a Luminoth Lore entry, and leave. A swarm of Hydlings is the only threat to Samus underwater, though the water may increase the danger because of its movement-restricting abilities.
