Bigfoot first appears in the mission "Team Player". The player must defend it from the OpFor attacking as it tries to deploy over a blown bridge, so the invasion can continue. After the player successfully defends it, the player will get in a Humvee and proceed with the invasion force. It is visible again when PFC Joseph Allen gets in the Humvee's Minigun. It will be on the left side of the bridge without the bridge turret gear. Bigfoot can be destroyed if the player slacks in defending it, especially when the enemies get on the far side of the bridge in a truck. It is possible Bigfoot survived the events of Call of Duty: Modern Warfare 2.
