Project Eden is a 3D shooter with an emphasis on puzzle-solving. Earth's population has grown, and humongous skyscrapers have been erected. The rich and average live in these skyscrapers, while the poor, deranged, illegal and criminals live at the very bottom, in the scummy area. The only time people go down there is to do foundation maintenance. Recently, a team of engineers has gone missing at the "Real Meat Factory", and the Urban Protection Agency (UPA) team is sent in.
