Plot

 * Caution. Spoilers are to follow.*

John Henry Eden is the main villain of the game. He is against James' Purity Project and orders James' and the Player Character killed. However, James sacrifices himself to let the PC escape. But later, the Player Character is captured. Eden invites the player to his quarters. It is revealed that Eden is actually a sentient computer. He orders the player character to release a virus into the Water Plant at Jefferson Memorial, threatening the player with death if he or she does not comply. The virus will kill all people that are not genetically pure. The player can activate the Plant without putting the virus in. However, the player will be killed for it. Lyons can be sent instead of the player to activate the Plant and will die instead. If the player is especially cruel, he may relase the virus, effectively commiting genocide.
