UAC Military Nightmare

UAC Military Nightmare was a WAD created by Terry in 2008 that requires Skulltag. The player has to open up the console and type "map uac01" in order to play this WAD. It consists of 18 levels, plus 1 additional level that replaces Map 05 of Doom 2. Terry's first single level wad under the name Dr. Tickle, was used once again in UAC Military Nightmare, this time called "The Crackhead's Forest".

Most likely a joke WAD, it received a poor response by many Doom fans due to the vulgarity of the scripts, often featuring threats to anally rape the player. The enemies consist of John Romero heads shooting BFG blasts that will kill you even in god mode, flame-shooting Ralphis heads shouting out "Spam spam! Spammy spam!" and a few more large pictures. This WAD was awarded Worst wad at the 15th Annual Cacowards.

Legacy
Over the years, UAC Military Nightmare has gone down in history as one of the worst wads ever made. When it comes to forum discussions debating on which wad is the worst, a good majority of people select this wad as the worst. Some compare this to Doomguy's Warzone when it comes to a certain level of terrible.

One of Terry's Lesser known monsters, Chin Cocko Man shows up in Doomguy's Warzone Gold Edition, it's 2012 remake, and Doomguy's Warzone Entire Roster Challenge as a part of the roster.

A spiritual successor to UAC Military Nightmare is currently in development with Terry and an unnamed YouTube user. Instead of creating this project in a WAD format, the authors are using Game Maker, simply for the sake of being able to say they created an FPS. This project appears to currently be in development hell, as Terry has posted nothing about it, barring a few screenshots, and seems to express minimal interest in it.

A fanmade sequel, UAC Military Nightmare 2 is currently being developed by Jack101 and is planned to be released sometime in November 2012.

Terry himself is currently developing an expansion pack known as UACMN Gold Edition, which raises the levels from 18 to 32, as well as adding various other new content.

The mini John heads which appear in the "The Good-Guy Hallways", shows up in Millennia Invasion as a tribute to the said level in UAC Military Nightmare.
