TNT: Evilution

TNT: Evilution, released in June 1996, forms one half of Final Doom, a commercial product which consisted of two 32-level add-ons for Doom II (the other being The Plutonia Experiment).

TNT: Evilution was completed in November 1995, and was to have been released for free. However, a publishing deal was brokered by John Romero, resulting in the commercial release of Final Doom by id Software. As of 2005, it is still on sale. 

The commercialisation of TNT: Evilution caused a certain amount of controversy amongst the Doom community, and Evilution is consequently one of Doomworld's "Top Ten Infamous Wads", albeit not for reasons of gameplay or level design.

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. Research continues with all security measures zeroed in on the gateway.

Later, the yearly supply ship comes 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.
