Metropolitan Mayhem is a 15-map mod for Duke Nukem 3D (Atomic Edition). It's themetically very close to the original first and third episodes (LA Meltdown & Shrapnel City) of Duke Nukem 3D, concentrating almost exclusively on classic urban-themed maps. The original plan was to spend at most 24 hours working on each map so map sizes vary from small to medium. In total the mod should provide an hour's worth of oldskool entertainment. If you liked Duke3D, particularly its city maps, you cannot miss Metropolitan Mayhem. The mod was designed by MetHunter, MRCK, Mikko Sandt and Merlijn van Oostrum.
The full 15-map Metropolitan Mayhem episode. Free source port EDuke32 is required to run the game in addition to a copy of Duke Nukem 3D Atomic Edition (in fact, all you need from the original game is a file called "DUKE3D.grp").
