Kor took part in Operation Leveler, were he was assigned to Green Troop, under the command of Pvt.Dominic Santiago. When they entered the main building, Kor ran into a security guard, and killed him with several blows from his machete. Kor then proceeded upstairs to secure the rest of the facility. He was later wounded during the battle, and was put on board a Marlin. However, that Marlin was hit by fire from a Khimera and began to sink. The other Marlin pulled alongside it, and most of the survivors were brought on board it, including Kor. The Marlin was picked up a Sea Raven, and Kor survived his wounds.
