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.
- In Pacific Rift, Sarah Hunter (orange "4TUNE" livery), Jackson Stone (woodland camo livery), Bob Fawley ("Tiger" livery), Sandy Campbell (turquoise/red livery) and Cap Boardman (grey camo livery) are AI Characters seen driving this vehicle.
- Furthermore, Cap Boardman has his name on the side of his vehicle and on his numberplate.
