This trailer shows off Just Cause 3 gameplay in spiffy 4K resolution in advance of next month's release of the action sequel (thanks DSOGaming). Word is: "Avalanche Studios have been busy squeezing every last drop of power out of their proprietary engine for the upcoming release of JUST CAUSE 3 on December 1st. The game can be seen firing on all cylinders, with all settings turned to overkill in this video running at a 4K resolution!"
