TNT: Evilution, released on June 17, 1996, forms one half of Final Doom, a commercial product which consists of two 32-level IWADs (the other being The Plutonia Experiment), similar to Doom II. The "TNT" in the title stands for "The New Technology" and is also the name of the mapping team who created TNT: Evilution. TNT: Evilution was completed in November 1995, and was going to be released for free. However, a publishing deal was brokered by John Romero, resulting in the commercial release of Final Doom by id Software.
