The Hidden Entrance is a location in Jak and Daxter: The Precursor Legacy VII. It is found at the end of the perilous trip through the Dark Eco Tube and is an entrance unbeknownst to the commanders of the North Crater Citadel. Oddly enough, although the name of the area is listed as you pass through it, the name is not present on the area list because it apparently contains no Precursor Orbs, Scout Flies or Power Cells. But 149 total Power Cells is a rather awkward number to have right? There's actually a hidden Power Cell around here.
