"Mason's son David leads JSOC's elite counter terrorist force investigating Menendez' links to a revolutionary new microchip made from Rare Earth Element Celerium."
— Mission description

"Celerium" is the second campaign mission in Call of Duty: Black Ops II where JSOC investigates a military compound filled with Cordis Die agents in the hopes of learning what Raul Menendez is planning. It is the first mission set in the year 2025.



In this mission, Joint Special Operations Command agents David "Section" Mason, Mike Harper, Javier Salazar, and Crosby infiltrate a remote temple to try to find info on Celerium. The mission begins with Section and Harper descending a cliff face via the use of nano-gloves and a large rope, then after a rendezvous with Salazar and Crosby, glide to the temple with wingsuits. Upon their arrival, Section sparks the attack, and the group fights their way through hostiles as they advance towards the main temple. The doors are then blown upon by either Section or Harper, and a secret, ultra high-tech bunker is found inside. The group fight their way through the bunker and find a Tacitus Corporation employee, Erik Breighner, locked in a crate. He helps them through some security doors and gives them access to a Celerium chip and tells them about Menendez's plot. Then he is shot through the neck before he can give a complete explanation. The group then fights their way through the remaining soldiers in the base, and after encountering other friendlies, Section hands over the Celerium chip to Tommy Briggs, who examines it as the mission ends.

Main article: Celerium (mission)/Transcript


  • After the player clears out the first enemy wave and goes to a cliff and goes to a cave, they can see a hammer stuck to the ground. This is a reference to Thor's hammer, Mjolnir.
    • If the player has not been spotted when the alarm sounds, with or without clearing out all the enemies, they will be able to interact with the hammer. Upon interacting with it, the phrase "You are not worthy" will appear on screen and the lightning around the hammer will disappear. In addition, the player will now have unlimited ammo for the Titus-6 if they have it equipped.[1]
  • Strangely, in the intro cutscene, the flashback that shows Alex Mason's struggle with Menendez seems to show him shooting Menendez directly in the face rather than the eye.
  • In the TV news appearing in the intro cutscene, Cordis Die organized an assault of rioters against Tehran and Pyongyang through social media. The assault happened in June 19th, the day Josefina almost died in the fire, and the date of Menendez's attack during the last missions of the campaign.
  • In Cordis Die's Twitter page shown in the cutscene, several interesting tweets can be noted such as:
    • Cordis Die says, "Come my friends... 'Tis not too late to seek a newer world." A quote from the Ulysses.
    • Cordis Die says, "A small rock holds back a great wave." A quote by Homer's The Odyssey.
    • Spov says, "Courage is not the absence of fear, but rather the judgment that something else is more important than fear." A quote by James Hollingworth.
    • Newsleworld says, "A new world, a new order. Seems Legit. Follow @cordis_die for real change.".
  • The player can destroy the temple door with a Titus-6 or other explosives before Harper does.
  • There is a usable lift in the area where enemies are first spotted.
  • Whenever an ambush scene is triggerred, it disables the player's Optical Camouflage.
  • The player cannot pick up the Assault Shield placed by Harper; the one from the dispenser can be taken instead.
  • If the player picks up the Assault Shield from the dispenser, the shield will act as a third weapon, allowing the player to carry more than two weapons. However, if the shield is planted onto the ground, when picked up again, it will replace whatever weapon the player is holding.
  • Several blue computer and television monitors can be found and destroyed inside the three enemy waystations outside the temple, and many more can be found and destroyed inside the research labs.
  • When Erik is shot through the neck and killed, the bullet comes from the right side of the room, but there is no enemy or entrance there.
    • Additionally, Section and his team instantly turn around to the enemies approaching from behind, even though that is not where Erik was shot from.
  • If the player has accessed the J-5 ASD, after Erik dies, J-5 becomes temporarily disabled, due to the enemies using an EMP grenade.
  • Near the end of the mission, Harper will complain about comms not working despite the fact that earlier he knew his team wouldn't be able to communicate while in the facility before entering it.
  • In the first area, Harper will kill one of the Mercs, but the others will not be alerted, despite the fact that his SCAR-H is not suppressed.
  • When fighting through the bunker, numerous scientist corpses can be found lying around. Many are actually still alive, but are wounded heavily. It is likely they were staff that the Mercs probably purged when J-SOC breached the compound. However, in one of the inaccessible rooms, one wounded civilian is apparently still alive and can be seen moving slightly.
  • The Celerium Device appears to be based on the idea of Quantum computers, which utilize the mechanics in Quantum physics, including Quantum entanglement.
