Just Cause games buried in landfill site
Just Cause and its sequel have been discovered buried in a landfill site.
One of the better Just Cause 3 easter eggs is the discovery that a landfill on the island of Medici has been used as a dumping ground for previous games.
The games are deemed "anti-Medician" and can be discovered by blowing up parts of the landfill, which you can find by following this handy map, as discovered by OnlyMogo.
The easter egg is of course a reference to Atari's notorious dumping of the E.T. game in the 1980s.
