The co-op content that the devs have informed us of, 'Legends of the Wasteland,' in my opinion sound quite linear. By this I mean, is it known whether while playing the 'Legends of the Wasteland' you and your co-op buddy will be capable of traversing the open world of RAGE together as you do in singleplayer, or will you be required to follow a linear path for each mission?
If anyone has heard anything from the devs on the subject then please post.
