The Jakob Project was made for the safety of the humans due to rising Maverick cases. Humans migrated to the moon, and the New Generation Reploids were tasked to use the elevators inside the Jakob Tower to transport materials to the moon.
Events that lead to Megaman X8
One of the elevators had malfunctioned and was sent crashing down, X is in the area when the door of the elevators ripped open, revealing not only one Sigma, but a whole army of Sigmas, X stands in shock when a purple-haired Reploid shows up in front of the Sigmas. He introduces himself as Lumine, who is the director of the Jakob Project and reveals that in fact, the Sigma Army aren't really Sigmas, but rather the New-Generation Reploids taking the form of Sigma to protect Lumine, who claims that New generation Reploids enjoy complete and total immunity to viruses, saying also that copying someone as dangerous as Sigma isn't risky at all. Later, Maverick Hunters X, Zero and Axl, who is now a full-time Maverick Hunter, are sent to investigate inside Point Galapagos, encountering a giant maverick resembling a crab which they encounter and defeat 3 times, destroying it in the final time. As they're about to leave, a barrage of missiles are sent to them, later revealing that it was Vile was the one to fire the missiles. Axl, who doesn't know Vile, stands surprised. While Zero explains that Vile used to be a hunter, and is now a Maverick, Vile then reveals a surprise for them, an entangled Lumine, who is seemingly unconscious (though it may be an act). Vile then leaves.
