24: The Game
Several hours into the game, Joseph Sin-Chung is taken into CTU where he tricks Chappelle into setting off an EMP bomb. Suddenly, troops burst into CTU and kill many staffers, including Sean Walker. They are led by Madsen. After downloading relevant data, Madsen turns on his employees and in the confusion, Jack Bauer breaks in and takes down most of the terrorists. He destroys Madsen's escape chopper, but Madsen kidnaps Kim Bauer in order to escape. He and Sin-Chung are picked up by an undercover Chase Edmunds and they escape. Madsen then calls Jack and tells him to break into Division and hack relevant files, and if he fails to do so, Kim will die. It is during a phone conversation that it is revealed Madsen once worked for Bauer. Later in the game, we find out that Madsen's plan is to set off explosives along intersecting fault lines near Los Angeles, causing a massive earthquake. Although Bauer, Tony Almeida and other CTU operatives are able to disarm the majority of the bombs, one still detonates, causing a sizable quake. After the quake, Madsen kidnaps Kate Warner under directions from his boss, Max. Max wants 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. Jack eventually blew the boat up, killing Madsen. Later, Kate was saved when Jack shot Max to death.
