Ram Shackles

B.J. uses the Ram Shackles to smash through a wall.

"A metal reinforcement rig protecting your upper body joints, elbows and shoulders. The Ram Shackles allow you to ram through obstacles, smash open doors and crates and pummel your enemies."

―In-game description.

The Ram Shackles are oriented toward the "Mayhem" playstyle and as such grant abilities mainly focused on enhancing B.J.'s capabilities in direct combat.

Abilities

• Rammbock: The main function, activated by sprinting. Running into certain cracked walls or metal grated doorways will smash through the wall, allowing quick entrance to previously inaccessible areas. Running into human enemies will knock them over and damage them, sometimes kill them outright or even causing their entire body to explode in a satisfying shower of gore.
• Sturdy: B.J. is no longer knocked over by explosions going off nearby, making enemy grenades and environmental explosions less dangerous.
• Cannon Arm: Grenades and hatchets are thrown much farther and faster. Hitting an enemy directly with a Handgranate will knock them down.
• Mechanic: One of the most useful of all the contraption abilities, allowing armour as well as health to be regenerated. Inactive when armour is reduced to zero, but picking up any armour boost will still trigger it; otherwise it engages automatically if no damage is taken for a few seconds. Like health regeneration, armour replenishment stops at certain intervals but can be bumped up to the next interval by collecting some; where health stops at multiples of 10, armour stops at multiples of five. Unlocked by completing Ritva Tuomivaara's side quest on the Eva's Hammer.

Location

If not selected as the initial contraption, they are found in the Bienville Street district of New Orleans during the relevant Übercommander mission.
