The second tier of Operation Deadbolt missions in Call of Duty: Modern Warfare 3 Zombies will have players track down and destroy a convoy of armored vehicles and eliminate the enemy mercenaries guarding the convoy to acquire a mercenary stronghold keycard. Players will want to gear up their operator for a rough fight using schematics and acquisitions, as the convoy is heavily guarded and the AI soldiers defending the truck will put up heavy resistance against players. It is highly recommended that players squad up and acquire high-level vests and weaponry before attempting this mission.
