The PS4 version will offer exclusive content, the Road Warrior Survival Kit.
A Mad Max game was originally revealed in March 2008 as a collaboration between God of War 2 director Cory Barlog and George Miller, the director of the Mad Max film franchise. In September 2010 it was reported that Barlog was working with Avalanche Studios on the game. Earlier this year, Avalanche founder Christofer Sundberg tweeted a screenshot of a game that he said last month was a "steampunk-style" title the team was once working on, but shelved.
Update: According to a press release from publisher Warner Bros. Interactive Entertainment, the game is simply called Mad Max and will be available in 2014 on Windows PC, PlayStation 4, Xbox One, PlayStation 3 and Xbox 360. It is an open-world third-person action game in which players take on the role of Max himself, trying to survive in The Wasteland against roving gangs of bandits. He'll use both typical action combat and vehicular combat.
"The Wasteland lends itself incredibly well to the high level of player freedom with which Avalanche Studios has become synonymous," said Sundberg in the press release. "This unforgiving environment inspired us to create a gritty and diverse experience where driving, fighting and scavenging are essential for survival."
