Devlin and Russell had previously been Subtech's employees in the 1970s, but when it was revealed their project to allow people to live at ocean depths for months was to allow the mining of Earth's seabeds, Russell left while Devlin stayed. By buying him out, Devlin now compromised Russell and effectively removed the last obstacle in their way. The Biosphere 4 'popped' to become a sealed environment in 2000, and Russell began the second phase of his project, to create Synths. This became his singular project, to the point where he almost eradicated the rainforest biodome due to a fungal outbreak. In 2003, Russell shared his research regarding the Synth4 plants to his colleague Sarah Parish, and asked for her help with the research. However, in 2005 he became too accustomed to the quick feedback loop of the biodome, and let the latest variant - Synth8 - be planted into the Biodome despite warnings from Sarah regarding their instability. After discovering that the Synths began attacking their babies within the growth chamber, Russell feared that he should have heeded Sarah's warnings though noted that oxygen could defeat the strongest of Synths. He pumps oxygen in killing his creations, and he fears what he has unleashed.

In the lead-up to the 10th anniversary of the Biosphere 4, Russell sent Devlin his proposed speech which pushed environmental issues. This angered Devlin who noted that he owned the project and Russell, and that it was seen as his baby at Subtech, so he would reassert his power if need be. In 2006 Devlin emailed Russell about that workers were arriving to construct a leisure resort complex in the advanced evolution biodome called Club Eden, which Russell was not happy about due to putting an end to his Synth experiments. When Devlin sent Russell a blackmailing video detailing how Russell had orchestrated an assassination of a colleague, Russell noted that Biosphere 4 was his home and that he would do anything in his power to protect it. The act of welding is turning oxygen into CO2 and the workers began to notice a change in the ecosystem, causing the air to become unfit to breathe and making workers suffer from respiratory issues and exhaustion. The workers began hearing and seeing weird things (the Synths), and Russell begins making trips to the biodome spraying fire extinguishers to lure out the Synths. Devlin instigates a policy where if the project wasn't completed, the workers would be sealed into the dome. Devlin also disconnects power from the biodome to the main control centre so Russell can't interfere. On December 10, 1997, the biodome wired up to the terminal so they could regulate their own atmosphere, taking the power away from Russell. Soon enough, a worker is killed by a Synth. On December 12, 2007, Devlin removed the ladder leaving to the cave out of the Biodome, effectively trapping the workers. On December 16, 2007, Russel issues his last warning and on December 20, Devlin tells the workers that everything's going to be okay. On December 23, 2007 two more workers disappear. Each of these deaths causes CO2 to be turned into oxygen. On December 24 during a Christmas party, Russell leaves a frantic message to the workers about the Synths, before a fire breaks loose which decimates the biodome. It is implied that Russel did this in an attempt to flush the biome clean by pumping oxygen in to kill all the Synths, as relayed in an audio recording. There aren't enough extinguishers to put out the fire. Russell shows up to help and the leader of the workers, who had previously been skeptical of Russell, attempts to follow him to safety but he and the rest die (accelerated by the alcohol). Russell barely escapes and passes out once he returns to the rainforest biodome, suffering from amnesia, which is where the game starts, on December 25, 2007.

Devlin sends Russell a video message saying that he knows Russell is responsible for the fire, and that he is furious and will destroy his life.

Upon the player nearing completion of restoring the atmosphere of Biosphere 4, Devlin sends Russell a final message detailing that thanks to Russel's efforts, Club Eden is ready for its first consignment of tourists, and that Subtech will kill Russel and posthumously ruin his reputation as the murderer of the Subtech worker crew and for being complicit in the assassination of his partner. Russell successfully escapes by un'popping' Biosphere 4, though the experiment proves that colonies can be created on other planets like Mars. While police wish to speak to him regarding the fire and assassination, Russell disappears without a trace. Meanwhile, Club Eden opened as planned and patrons noticed their partners going missing, which Devlin put down to administration error. Devlin is later killed by a Synth, and the Synth spores spread out into the human world.
