Before The Game
Several hours into the game, Joseph Sin-Chung was taken into CTU where he tricked Ryan Chappelle into setting off an EMP bomb. Suddenly, mercenary troops led by Madsen burst into CTU and killed many staffers, including Sean Walker. After downloading relevant data, Madsen turned on his employees and in the confusion, Jack Bauer broke in and took down most of the terrorists. He destroyed Madsen's escape chopper, but Madsen kidnapped Kim Bauer in order to escape. He and Sin-Chung were picked up by an undercover Chase Edmunds before they escaped. Madsen then called Jack and told him to break into Division and hack relevant files. If Jack failed to do so, Kim would die.
Madsen later revealed his plan to set off explosives along intersecting fault lines near Los Angeles, causing a massive earthquake. Although Bauer, Tony Almeida and other CTU operatives were able to disarm the majority of the bombs, one still detonated, causing a sizable quake. After the quake, Madsen kidnapped Kate Warner under directions from his boss, Max. Max wanted to use Kate as leverage in order to get her father, Bob Warner to help Max smuggle nukes out of the country. However, thanks to work from Chase and Jack, the plan failed and Madsen attempted to escape by boat, but Jack fired on it, igniting the gasoline and blowing up the boat along with Madsen, killing him.
