It was announced earlier this week that the mod would launch before the end of 2013.
A final beta test of the mod will run from December 7-14, giving the team a chance to identify and fix any final issues in preparation for the full launch. Anyone interested in trying the mod during the beta test can apply for a Steam key here.
CVG's Just Cause 2 review concluded: "In stark contrast to the first game, you'll never be at a loss for something to be getting on with. You never feel compelled to do anything by the book and every session you play, you'll find yourself concentrating on a new part of the game, continually getting distracted by something else along the way. Save for the combat, Just Cause 2 is everything we hoped the original was going to be."
