Jakob is a setting important to the plot of Mega Man X8. It's an orbital elevator built in the Galápagos Islands as part of the Jakob Project. The Reploid in charge of the project, Lumine, was captured by Vile at the beginning of the game and Sigma took control of the Jakob Project. After defeating the eight bosses, the Maverick Hunters use the elevator to go after Sigma who has stationed himself on the Moon, also fighting against Vile at the top of the tower.
