Kassar

Dr. Kassar is a character in Call of Duty: Ghosts Extinction mode. He is a scientist who worked for David Archer aboard the Stormbreaker.

Events before Mayday
Kassar was ordered by David Archer to interrogate Samantha Cross about the Arks and why she released the Cryptids back in Alaska. During the interrogations, he saw that Cross start to become more dangerous everyday. He reported to Archer that Cross is no longer human and should be dead by now due to her becoming "unstable". When he told Archer that he'll put her down due to her causing the entire crew on the Stormbreaker to have violent nightmares, Archer theatens that he'll fed him to the Cryptids just like the person who tried to kill Cross when she was asleep. On November 25th, 2017 just as they were at reach of Ball's Pyramid, he was finishing up interrogating Cross about if the builders of the Arks where extinct and how many Arks are there worldwide. Cross laughed saying that they kept it in secret and they created a "guardian" to protect the Ark at Ball's Pyramid as the Cryptids started to escape their imprisonment aboard the ship.

Death
As the Cryptids headed for Kassar and Cross, Kassar begged Cross to not kill him and that he'll help her, but she says he's already helped. She then gets an idea on how to repay him as she orders the Cryptids to swarm him and tear him apart, killing him.
