Dante's Gate is a single-level PWAD designed by John W. "Dr. Sleep" Anderson. In an era when level editing tools were fairly primitive, it distinguished itself by a strong emphasis on theme and mood, as well as by technical soundness. It is now considered an all-time classic. At least five versions of the map are widely available: The first three WADs replace E1M1; the other two replace MAP02. The level appeared in Maximum Doom as DANTE2.WAD, DANTE21.WAD, and DANTES2.WAD.
