This directory contains levels from authors in the DOOM community who have submitted them to TeamTNT for inclusion in their list of levels that use The Return's resources. Please read the text files to be sure you know what requirements there are for running the levels. Some may use "source ports" such as Boom or ZDoom, for instance. The primary resource file is RETRES.WAD, which you can get here zipped in RETRES.ZIP. See http://www.teamtnt.com (then link to Return) for a summary of these levels and other information including how to get your own levels included here.
