"Hack into enemy security sentries and reach the subway in time."
— Level Description

Firewall is a two-player Special Ops Mission Mode challenge in Call of Duty: Modern Warfare 3. It takes place in London, and is based off "Mind The Gap".

Overview

This mission can only be played with two players. One player will be on foot, while the other will be in control of multiple security sentries which are laid out across the map. The player on foot must reach the subway in five minutes, while the other player provides cover with mounted Sentry Guns. The covering player can view two different camera angles at a time, and the player on foot must use computers at four different checkpoints to be able to proceed, as well as let the other player change camera view. However, on two points the player on foot must clear an area without covering fire, as the Sentry Gun's view cannot reach the areas.

Trivia

  • Along with the mission Fire Mission, this is one of the only two mission that can only be played with two players.
  • It is possible to complete the mission in four minutes and a fraction of a second. Doing this will say the mission was failed, but the score table will say the mission was a success.
  • The silenced SPAS-12 uses the Call of Duty: Modern Warfare 2 model.
  • This mission, Hit and Run, Invisible Threat, and Fire Mission are the only Mission Mode challenges where the players have different starting loadouts.
