Many of the newer missions have their maps noted on the wiki. If you look at Infernia, on the right side of the page near the beginning of each mission, it has the map name: http://paragonwiki.com/wiki/InferniaIt only gives the name, not the full path like Pengy gave, but it's a start if there's no other info.
okay I created the folders that I did not have, and placed them in this order putting all popmenu downloads inside of the menu folderContents > Resources > transgaming > c_drive > coh > data > text > English > Menus still nothing
I do not believe it is part of the standard maps, but Guy Perfect had posted the files and instructions needed to go there.Unfortunately, I cannot recall the details or find the post at the moment. Sorry.
