E1M4: Arachnoid is the fourth map of URE2020: Unexpected Retro Experience. It was designed by Zylinderkatze and uses one of the following music tracks: "Demons on the Prey" by Robert Prince (base WAD), untitled track by Amaury Laurent Bernier (when loading base WAD with URE2020A.WAD) or "The Cut of Your Gib" by Nathan Maxx (Lippeth) (when loading base WAD with URE2020L.WAD).
