The Variable Armor Lock is a prototype armor enhancement used by Agent Washington. Unlike the original Armor Lock, which required the user to be stationary, the Variable Armor Lock allows the user to decrease the strength of the Armor Lock, allowing for admittedly sluggish movement at a drawback of damage bleeding through. At higher settings, the user is unable to move, but is nearly invincible. It is also capable of releasing a shockwave of energy, temporarily disabling the Variable Armor Lock for several seconds.
The Variable Armor Lock is first seen being used by Washington during the Assault on Project Freelancer: Rebirth. He uses it to shield a wounded Agent Maine from weapon fire. It's ability to create a shockwave is then used during Mission: AI to send 10 soldiers flying through a window.
