The eco mine is a location featured in Jak 3. It is a large quarry full of scaffolding and mining equipment which Jak theorized was used by Mar to harvest eco energy for Haven City. During Jak 3, Jak visited the eco mine via the sub-rails from the Monk Temple. While exploring the eco mine, Jak encountered several rare metal heads and other returning creatures from Jak II, and eventually found a pair of greaves, a component of the Armor of Mar set. He then escorted a bomb train which he used to open a path to Haven City. In his way, however, was Veger and his Precursor robot, the latter of which he defeated and re-entered Haven City.
