Trivia

 * The ending of this mission bears a resemblance to Call of Duty 4's ending in where, the playable character is wounded and dragged to safety by teammates, put on a helicopter by a Russian Loyalist and during which 3 of the characters who helped the others escape die. Albiet with explosions and not gunfire.
 * After killing the man in the Elevator, he drops a G36C with Hybrid Sight, Silencer, and Grenade Launcher. It cannot be picked up, nor can the player resupply ammo for his G36C Red Dot.
 * During the pursuit of the President, the player can't kill the guards who are escorting the President to the bottom floor with any weapon.
 * This level includes the second appearance of the Bagger 288 mining excavator in the series; the first was Vorkuta.
 * There is a typo at the end, where Vladimir Makarov is written as "Vladamir Makarov."
 * This is the only point in the Modern Warfare series where a character pulls out dual wield pistols and fires them in separate directions; this is performed by Grinch at the climax of the mission.
 * This the only mission where the Throwing Knife is seen. Used by Sandman in the climax of the mission.
