Plot
In this mission, J-SOC agents Section, Harper and 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 specially designed suits. 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 hi-tech bunker is found inside. The group fight their way through the bunker and find a Tacitus employee, Erik Breighner, locked in a crate. He helps them through some security doors and gives them access to a Celerium chip and tells of Menendez's plot, but 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 Briggs, who examines it as the mission ends.

Trivia

 * The mission takes place on April 20, Viktor Reznov's 112th birthday.
 * When sneaking up on Guards at the beginning of the mission, Harper has a silenced SCAR-H but once inside the facility, the silencer is gone.
 * There is a usable lift in the area where enemies were first spotted.
 * If the player picks up the Assault Shield from the dispenser, the shield will act as a third weapon, allowing players 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.
 * If the player knifes the crate where Erik Breighner is hidden, blood will splat out of it like the player killed him, but he will still be alive when the crate is opened.
 * 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.
 * Cordis Die says, "A small rock holds back a great wave." A quote by.
 * 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.

 * The Twitter page shows the site's copyright notice dated 2011.
 * The player can destroy the temple door with a Titus-6 or other explosive before Harper does.
 * If the player stands between Harper and the temple door when Harper shoots it, the flechettes might hit and stick to the player, killing him in the coming explosion. Even if the player stands far from the door, it will still crumble however.
 * When the tree falls down and Salazar tries to help David, the player can hear a very short beginning of a soundtrack: Paris Siege from the MW3 soundtrack.
 * After the player clears out the first enemy wave and goes to a cliff and goes to a cave, one can see a hammer stuck to the ground. This is a reference to Thor's hammer, Mjolnir.
 * If the player has accessed the J-5 ASD, and after Erik dies, J-5 seems to be disabled as if an EMP was thrown.
 * The DSR 50 is obtainable in this mission, besides Ship Wreck.
