My personal opinion, is to do what the site says to do and try some of them. ROTT LE uses the rtl. file system, the other games use the .wad file system so I don't know if they will work with this ROTT ver. Many player levels are right here to down load and play. Several I have tried are really well made.

Well, I know what I'm gonna do with 'em.

1. Download them all.
   
2. Import the maps into Map Packs in the Map Editor.
   (One pack for Single Player, one pack for Comm-Bat™.)
   
3. Fix 'em up with the proper author info and whatnot.
   
4. Enjoy them.

𝚁𝚃𝙻 files can also be loaded using the –𝚏𝚒𝚕𝚎𝚛𝚝𝚕 command line parameter, but, I don't think RottEX currently supports custom assets from 𝚆𝙰𝙳 files. So, boo.

Could you please put them in the workshop after adding the proper info? That'd be wonderful
