Project Eden Windows, PS2, XBOX game

Project Eden is a third/first-person shooter co-operative puzzle game set in a large futuristic metropolis. In the future, the world is over-populated, giving the human race only one option - to build into the skies. Unable to destroy previous structures, buildings are only built upon each other, forming a large underworld of decaying cities.

The only people known to move about these abandoned cities are those who maintain supports for buildings higher-up. Recently, technicians go missing, and a UPA (Urban Protection Agency) team is dispatched to find their whereabouts. The small job turns out to be a deep-rooted hunt that takes them to the lowest depths of the dark underworld.
