We've all been calling (him? her?) the dinosaur Rexy, but I'm not sure if @Leeloo has confirmed that as official.
yes it is many other great maps as well --- Post updated --- there is a good modified etk map that includes offroad area and acces to the castle but no highway
Let me add, we also don't know how long the new contnt has been in the works. They're teasing it now, but it could have been in progress long before that. I forget when the original comment by tdev (i think it was him at least, correct me if I'm wrong) about the new map being sunny & dry was, but I think it was a while ago now and we don't know if they were already making the map or in advance planning stage at that time. They/ them
"Rexy" is a .dae mesh representative of a chunk of fibreglass. "Rexy" is, quite categorically, an "it". and a damn sexy one at that...
Surely at this point we should expect maps to compliment the upcoming campaign (given that it's somewhat present within the game already) I'm assuming the map will likely be set some place between WCUSA and Utah, as a progression step between the two.
