TNT: Revilution (TNTR.WAD)

In 2009, Whoo opened the doors for TNT2, what was to be a spiritual sequel to TNT: Evilution. What followed was one of the longest and most protracted and most importantly PUBLIC development cycles in the community. Somewhere along the way, Steve Muller aka "Kyka" took the reigns of development along with a few other forum regulars who really wanted to see TNT2 make it to completion. I distinctly recall playing a gorgeous TNT2 demo map from Xaser. His teaser generated a lot of buzz for the project, but certain folks including a late-returning Whoo looked at the direction that Kyka had taken TNT2 and were vocally...dissatisfied. Somewhere after all the name-calling and aspersions, when the project heads could speak a bit more civilly in public, there was a project split in 2014, founded upon some sort of a level draft where levels were split up like dividing property during a divorce. A bit more level-headed than the divorces I've heard talk of, really. This is where Revilution's story begins, as a TNT2 spinoff.

Mayhem 2048 (MAYHEM14.WAD)

Mayhem has been a Doomworld institution since 2012. TheMionicDonut had a dream, and that dream was to get as many people as possible to make a map over the course of a month - May, of course. The other part of the institution is to take as long as humanly possible compiling and fixing the darn thing, with 2012 seeing release in November and 2013 in March... of 2014. As of the time I'm writing this, the 2014 installment - Mayhem 2048 - is still not finalized, but maybe by the time this is published they'll pull together and slap the thing on the archives (EDIT: done as of Nov. 27!).

Realm of Chaos (RLMCHAOS.WAD)

Realm of Chaos, released in 1996, is another one of those Doom II megaWADs from the golden age of modding. Its major claim to fame is that it was developed by a team of Macintosh users, hence their name. As Steve Duff offered in his retrospective, Realm of Chaos showcased the best that the Mac scene had to offer because it showcased virtually the ONLY authors the Mac scene had to offer. Clint Sago started the project but pretty quickly discovered that, despite his enthusiasm, his talents were lacking. Rob Berkowitz served as his "executive officer", filling out a large portion of the lineup as well as the role of direct leadership. Realm of Chaos is pretty comparable to its peers, in spite of the dodgy editor they had to work with, and took about as long to build as Memento Mori. It's not quite as crazy, or complex, but there are some gems to be had here.
