HammUEr, a Hammer/Worldcraft map importer for Unreal Engine

[turfster]

1. It should (assuming you have the original vmf files)
2. No, Source 2 saves maps in a new binary vmap format, and the Dota2 version of Hammer has no option to export to the original .map or .vmf format.
   (I might add an importer for this in a future version, but at the moment, the answer is no)
