TNT: Evilution

TNT: Evilution, released on, forms one half of Final Doom, a commercial product which consists of two 32-level Doom II IWADs (the other being The Plutonia Experiment). The "TNT" in the title stands for "The New Technology", and represents the name of the mapping team, TeamTNT, who created Evilution. It was completed in November 1995, and was to have been released for free. However, a publishing deal was brokered by John Romero the night before its planned release, resulting in the commercial publication of Final Doom by id Software. This commercialization of TNT: Evilution caused a certain amount of controversy within the Doom community, and Evilution is consequently one of Doomworld's "Top 10 Infamous WADs", albeit not for reasons of gameplay or level design.

Evilution has a much more technical theme with levels that are akin to real buildings, versus Plutonia, whose floor design tends more toward a natural landscape feel.

Eleven levels from the IWAD are featured in the Sony PlayStation version of Final Doom.

Story
In TNT: Evilution the UAC once again are intent on developing and experimenting with dimensional gateway technology. They set up a base on Io, one of the moons of Jupiter, with a solid detachment of space marines for protection. The marines do their job well: when the first experimental gateway is opened they annihilate the forces of Hell. Anything that came through the gateway was immediately destroyed by the marines, and so research on the gateways continued.

Later, the yearly supply ship came earlier than expected, and looks strange and unusually large on the radar. 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. The ship's enormous gates open to unleash a rain of demons on the base. Quickly, the whole base is overrun, and everyone is slain or zombified.

The Doomguy, now in command of the marine deployment, has been away on a walk, and has thus escaped death or zombification. After being attacked by an imp he rushes back to the base, where he sees the demonic spaceship still hovering above it and realizes what has happened. Then he swears that he will seek revenge for his slain troops, and sets out to slay as many evil creatures as possible.

Levels
As in Doom II, the levels can be divided up into four sets. There are three loose episodes each defined by its own sky texture (1-11, 12-20 and 21-30) and two secret levels (31-32). The player is presented with a text screen in between the episodes (before levels 12 and 21). Additional textual interludes appear before level 7, before each secret level, and at the conclusion of the game. The designers of each map were unveiled by Ty Halderman in a at the Doomworld forums in 2004, showing that several level designs were shared between multiple authors.
