C.E.B.E.

C.E.B.E., or Chemically Engieneered Biofactor Element, is a soldier who was genetically modified to be able to fight in extreme environments. He can withstand 4.5x the damage of a regular human. He wound up fighting zombies with the gang when they came across his droppod in the mountains of Colorado, a day before the intro starts.

Trivia

 * Although he can withstand 4.5x the regular human, he still only survives 2 hits in-game without Jugger-nog or any health boosts.
