Under Siege 2: Dark TerritoryEdit
Penn is the leader of a group of highly trained mercenaries hired by Travis Dane to help seize control of a Grand Continental passenger train travelling through the Rocky Mountains from Denver to Los Angeles. Penn and his men hold the passengers hostage so that Dane can use the train as a moving base for his plan to destroy the Pentagon in Washington using a satellite weapon named Grazer One. When ex-Navy SEAL Casey Ryback, who happens to be on board the train, starts killing off Penn's mercenaries, Penn tries to track down the culprit. Penn had known Ryback during their experiences and is one of the very few people whom Penn finds intimidating.
When he realizes that Ryback is behind the attacks on his men and has put him on the defensive, he takes Ryback's niece, Sarah, hostage and waits for Ryback to confront him in one of the carriages. Ryback finds Penn, and they both throw down their guns, agreeing instead to engage in a one-on-one fistfight. The battle leads them to the train's kitchen, where Penn tries to kill Ryback with a large knife, but Ryback gets Penn in a tight headlock and breaks his neck.
