The Atlas Pacifier is a Mud Plugger in MotorStorm: Pacific Rift. It takes the appearance of a modified Humvee with larger axles and tires, a front brush guard and large vertical exhaust pipes on the sides.
- This Mud Plugger seems to resemble the Atlas Jackhammer. Although the Pacifier is much longer, it lacks the roll cage that completely surrounds the body, and has four doors instead of two.
- In the "Veteran" motion comic for MotorStorm: Apocalypse, Big Dog is seen driving a Humvee-type vehicle with striking resemblance to the Pacifier.
- The AI Character Cap Boardman has his name on the side of his personal livery and that livery's license plate.
