The Doomguy, now in command of the marine deployment, has been away on a walk, and has thus escaped death or zombification. Quickly, the whole base is overrun, and everyone is slain or zombified. The ship's enormous gates open to unleash a rain of demons on the base. The personnel of the base go out to behold the terrible truth: it is a spaceship from Hell, built of steel, stone, flesh, bone and corruption. Later, the yearly supply ship came earlier than expected, and looks strange and unusually large on the radar. Anything that came through the gateway was immediately destroyed by the marines, and so research on the gateways continued. The marines do their job well: when the first experimental gateway is opened they annihilate the forces of Hell. They set up a base on one of the moons of Jupiter, with a solid detachment of space marines for protection. In TNT: Evilution the UAC once again are intent on developing and experimenting with dimensional gateway technology. TNT: Evilution has a much more technical feel with levels that are akin to real buildings, versus The Plutonia Experiment, whose floor design tends more toward a natural landscape feel. The commercialization of TNT: Evilution caused a certain amount of controversy amongst the Doom community, and TNT: Evilution is consequently one of Doomworld's " Top 10 Infamous WADs", albeit not for reasons of gameplay or level design. However, a publishing deal was brokered by John Romero, resulting in the commercial release of Final Doom by id Software. TNT: Evilution was completed in November 1995, and was going to be released for free. 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, 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.
