Editing Final Doom (section)

==Development==
The original ''TNT: Evilution'' [[Doom modding|megawad]] was created by [[TeamTNT]], a group of WAD-making hobbyists who were active on the 'advanced ''Doom'' editing' [[mailing list]]. It was scheduled to be released online as a free download on October 25, 1995. However, just 5 hours before its release [[John Romero]] contacted the leader of TeamTNT, Ty Halderman, with an offer to acquire and sell the project as an official product."<ref name="halderman1"/> The 2–3 dozen core members of TeamTNT formed a legal entity and completed the sale to [[id Software]] a couple weeks later.<ref>{{Cite web |date=1998 |title=Ty Halderman Interview - Page 2 |url=https://5years.doomworld.com/interviews/tyhalderman/page2.shtml |access-date=2024-08-24 |website=Doomworld}}</ref> [[GT Interactive]] secured worldwide rights to distribute the game in February 1996.<ref>{{cite web|url=http://www.thefreelibrary.com/GT%2BInteractive%2BHeralds%2B%27The%2BiDs%2Bof%2BMarch%2C%27%2B%27Final%2BDoom%2C%27%2B%27Hexen%27%2Bfor...-a017920455|archiveurl=https://web.archive.org/web/20120928100426/http://www.thefreelibrary.com/GT+Interactive+Heralds+'The+iDs+of+March%2c'+'Final+Doom%2c'+'Hexen'+for...-a017920455|title=GT Interactive Heralds 'The iDs of March,' 'Final Doom,' 'Hexen' for Mac, 'Heretic Master Levels,' 'Doom II,' 'Hexen Deathkings,' and 'Ultimate Doom'; Company's Spring id Games Readies Players for QUAKE Fall release|website=[[Business Wire]]|archivedate=September 28, 2012|date=February 5, 1996|accessdate=February 4, 2024|via=[[The Free Library]]}}</ref>

Brothers Dario and Milo Casali, who had contributed eight [[level (video games)|level]]s to ''TNT: Evilution'', were assigned the task of creating what became ''The Plutonia Experiment'' after having sent an eight-level WAD they had created to [[American McGee]] and managing to impress him along with the rest of the id Software crew. They created 16 levels each for ''The Plutonia Experiment'' in four months time, and submitted them in January 1996. Unlike their contributions to ''TNT: Evilution'', which were edited by id Software before the final release,{{Efn|Additionally, four of their eight levels were excluded from the final release because they were too big to run on 8MB of RAM, ''Final Doom''<nowiki>'</nowiki>s minimum system requirement.}} no revisions were made to or requested for these 32 levels.<ref name="casali2">{{Cite web |date=1998 |title=Dario Casali - Page 2|url=http://5years.doomworld.com/interviews/dariocasali/page2.shtml |access-date=2024-08-24 |website=Doomworld}}</ref>

When asked post-release about reports that many players found the ''Plutonia'' levels too hard for them, Dario Casali stated that "''Plutonia'' was always meant for people who had finished ''Doom 2'' on hard and were looking for a new challenge. I always played through the level I had made on hard, and if I could beat it too easily, I made it harder, so it was a challenge for me."<ref name="casali2"/>
