WK has just posted an article about the map that will be included in the DoFP action pack, and I just have to say that it looks amazing.
http://www.wizkidsgames.com/heroclix/marvel/gameresources.asp?cid=41144Essentially, the map (which shows a destroyed X-Mansion) will connect with the outdoor map from the Danger Room starter to make an even bigger battlefield. As if that wasn't enough to hold your games, if you have an extra Danger Room map you can make it even bigger. Using special map scenario rules, there is a set of elevator spaces in the DoFP map that will take a character down to matching spaces in the Danger Room indoor map (the training area of the same name). Allowing for huge multi-person battles, this could be one of the kewlest things to come out for heroclix in a while. I personally can't wait, of course this means I have to go and buy another Danger Room for the extra map.
Enjoy!
