... with Frank Mancuso Jr. (who was also busy producing Friday the 13th: The Series, which, interestingly enough, was actually rated just behind the first season of this show), who admitted that he never really watched many of the episodes of the first season. This combined with different writers made for a season that was terribly inconsistent with the first. Just about every detail of the first season was either changed completely or just deleted altogether (such as the Biblical reference and black humour). Even the show's name underwent change as it was now fully titled "War of the Worlds: The Second Invasion".

All the changes between seasons are far too numerous. First, the modern day setting was now shifted to a not-too-distant future of "Almost Tomorrow" where the world had since spiraled into a dismal state with its economy, environment, and government all beaten down. Of the few characters that returned for the second season, most were killed off in the season premiere. The two saddest demises were that of fan favourites Norton and Ironhorse. Also sent to their death were the aliens of the first season. The Advocacy and their lot (all incorrectly referred to as soldiers) were sent to execution by a new race of aliens, the Morthren. Despite the fact that their planet is clearly stated to be Morthrai, they are still inexplicably tied to the first season aliens whose planet was named Mor-Tax. Planet name change was but one aspect altered with the aliens. Virtually much of what made up personality traits of the Mor-Tax race were nonexistent with the Morthren - 3 seemed to be nothing special to them and "To Life Immortal" was never uttered. In fact, their belief system centred on a strange deity called the Eternal Spirit of Morthrai (simply called "the Eternal" throughout the season), which seemed to erase the existence of the Council as their leader. Many other problems with the continuity between seasons only grew as the season went along as many things with the aliens' backstory kept changing, each time distancing from facts not only established in the first season and film, but even those rooted in the H.G. Wells novel (some elements of which the first season had tied into its mythology). These drastic changes were never even explained, even when the show had a conclusive finale.

Whereas bacteria and radiation were constant problems for the Mor-Tax, the Morthren had suddenly found a cure-all means for this by transmutating into human bodies, a process that was only noted in the first episode, but never explained in any detail. With this, they forwent the ability to possess human bodies, retaining only one human body. Their equivalent of body-swapping was a cloning machine that would make exact copies of someone, only differing that the duplicates would be loyal to the Morthren cause and physically tied to its original. Ironically, as sores were the telltale signs of alien possession in the first season, a lack of scars or any physical flaw was a telltale sign of a clone as the Morthren were fixated with perfection. While the Eternal is their god, the Morthren are led by Malzor (played by Denis Forest, who had a large part in the Season 1 episode "Vengeance is Mine"). Just under him was the scientist Mana (Catherine Disher, whose husband also played a major role in a Season 1 episode) with Ardix (Julian Richings who appeared briefly in "He Feedeth Among the Lillies") as her assistant.

Meanwhile, with General Wilson missing, the Cottage destroyed, and two team members lost in battle, the remnants of the team, with mercenary John Kincaid (Adrian Paul), seek shelter. They take up base in an underground hideout in the sewers. And the aliens weren't the only characters to change. Harrison seemed to have lost touch with his kooky nature (yoga positions, tuning forks, etc.), and for a man who turned down every offer of a gun from Ironhorse, he now carries one with no second thought. Meanwhile, Suzanne, a microbiologist, suddenly seemed incapable of even baking a simple cake with her daughter Debi (Rachel Blanchard) slowly starting to become the star of the series. The show's theme of warfare between two races, and all the prejudice that went with it, had been taken over by a theme of a bleak life on a desolate world.

While the radical changes were often claimed to be for the better of the show, many fans were turned off for many reasons. Ultimately, the ratings were so poor that the series had to wrap things up just two episodes shy of a full season.
