Does this come with the level designer?

If so, will it work on OS X as well?

I'm unsure what is included in the Mac version but on the Windows version, if you check the Classic directory you will find Build.exe which is for making maps. You could probably run that in DOSBOX for the Mac version too.

Use mapster 32 which comes with Eduke32 which is a source port for duke nukem 3d and mapster32 is basically just a source port of Build.exe. It has modern pc support so dosbox isn't necessary to make it work. I'm sure by arranging files in a certain ways you can probably use the megaton edition files to work with it.

Thanks for the replies. I wiped os x and put windows 7 back on my PC. Gaming just isn't the same.
