The Ultimate NMD

The Ultimate NMD (or The Ultimate Needs More Detail) is a 2009 megawad for Doom containing 27 new levels created by Fiend. The levels are designed in the style of original levels, however they are much smaller in size and not as detailed as the levels that were getting released at that time, hence the name "Needs More Detail" given for the wad. The previous two episodes were released separately in 2008 as "Needs More Detail" and "Needs More Detail II", while the final episode was released on June 30th, 2009 as "The Ultimate NMD" and included the previous two episodes as well, with little to no changes made to them.
