Earth 2150: Lost Souls is the second sequel to the real time strategy game Earth 2150. While it is a stand-alone game, many consider it the second expansion pack because it does little more than provide new missions, and weapons. The story takes place alongside the original game's story. Lost Souls was released in 2002.
Premise
Earth's final war is in full swing. The United Civilized States, Eurasian Dynasty, and the Lunar Corporation fight over what is left of the world's resources in order to escape the blue planet before it is destroyed. After most of Earth's citizens escaped with the evacuation ships, the people left behind became known as the Lost Souls. They didn't give up on escape and continued to fight amongst each other. They hoped to scrape together the dying planet's meager resources and find a way to escape and get revenge on those who had left them behind.
Story
The game plays nearly the same as Earth 2150 with new campaigns. Unlike the original game, the campaigns are now tied together in a chronological order:
Part I - ED campaign
General Fedorov, General of the Mobile Team (MEK) is called upon by Czar Vladimir II to gather crucial resources from Lunar Corporation territory in Finland in order to complete manufacturing of the space shuttle electronics. As the LC base was heavily defended, Fedorov took a detour, attacking the base from the east side where it was most vulnerable. His next task was to defeat a UCS incursion in Korea. The Czar theorised that the reason behind this attack was that it was a major production center, intended to build a strike force to destroy the shuttle silos in China, stranding their enemy on the dying planet.
The egotistic Czar sent Fedorov on a counter offensive in Bulgaria against the massive UCS presence there. Although Fedorov knew that this attack was ill-advised at the least, he carried it out, destroying a major UCS base but suffering heavy casualties. He was surprised to learn that there were traitors in their midst, who had an encampment in Russia. Begrudgingly, he took a platoon of heavy armor to deal with this threat, which turned out to be a foul trick. The alleged "traitors" were the forces of General Ivanov, a long-time friend of Fedorov and loyal to Vladimir II. While the two were confused over why the Czar wanted them to kill each other, they were ambushed by loyalist forces. After destroying their base of operations, the generals learned about Vladimir's plan: the shuttles were only able to carry about one million people to Mars, which was only a fraction of the total Eurasian population. As such, Vladimir planned to only take his most loyal minions with him. The popularity of the two generals have risen recently, while his waned and he didn't want to risk losing his power in space due to a coup. For that reason, he wanted to leave both of them behind. Obviously, the generals couldn't let this happen.
The rebels planned an attack against a dam in the middle of the former Russia as a ruse. They knew that downriver was a major agricultural area where food supplies for the shuttles were being grown. By destroying the dam, the ensuing flood would destroy most of these and delay the launch. In addition, this act of terrorism would draw away enough forces from China to attempt an attack on the launch complex. Their plan was successful, however there were two problems: the response teams were larger than expected, and UCS troops appeared in the region. The rebels quickly deduced that the UCS had something in the area which the loyalists did not wanted to fall into rebel hands. The something turned out to be a cache of UCS research data previously hidden underwater.
The response teams also served as a delay: by the time the generals reached the launch complex, they had only two and a half days to capture China's most heavily defended installation (although this later turned out to be false intelligence; the mission is impossible to do in the allotted time, so the developers removed the limit but "left" in a fake timer). When they finally succeeded, they learned that they were fooled yet again. The silos were empty. Some time later, the generals witnessed the shuttles blast off from behind a nearby mountain range.
