Continuing the theatrics and explosions of previous entries, Square Enix has just revealed a story and gameplay trailer for the upcoming Rico-fest, version 4. Just Cause 4 will follow Rico's exploits on Solis, a "huge South American world home of conflict, oppression and extreme weather conditions" (there are more than 1,024 square kilometers on this title), as he hunts down "the truth about his past, at any costs". To do so, he'll have to defeat a high-tech, private military organization, dubbed Black Hand. Catch the trailer below as an entrée to the games' launch, scheduled for December 4th.
