Effects

Grants an extra 25% damage dealt to robots. Also, entering sneak mode and deactivating a robot from behind permanently shuts it down.

Robots that can be disabled

Additional dialogue

Additional dialogue options are unlocked with certain robots with this perk. These often bypass Speech checks:

Notes

  • A deactivated robot cannot be targeted in V.A.T.S. However, the unit can still take damage, and destroying one will give the same experience and loot as normal. Every attack on a deactivated robot while sneaking will register as a "sneak attack critical," regardless of the player's location or level.
  • Making physical contact with a deactivated robot while sneaking may still alert other robots in the vicinity to the player's presence, just as if the robot were fully active.
  • When given the option to disable a sentry bot, it also gives the option to "talk" to the robot, as if one was interacting with a friendly robot, such as Wadsworth. However, one cannot engage the robot in conversation.
  • For deactivating a robot using the perk, it is sufficient to be crouched and behind it. As opposed to the perk's description, it is not necessary to be [HIDDEN], i.e. close up and unnoticed. The player character can in fact charge a hostile robot, crouch, circle strafe and disable it while it is circling about weapons blazing.
  • Automated turrets are scripted as robots and can be disabled with this perk. While in many cases they are out of reach, ceiling-mounted turrets can be disabled if the player is able to reach them by jumping while crouched.
  • When sneaking up on a robot with this perk, if "talk" is selected, it talks to the player character and does not attack. (e.g. a sentry bot, when the talk selection is selected, it will say "Do not interfere with security operations.")
  • Sergeant RL-3 can be disabled with this perk.
  • Deactivating a robot will not cause any of its allies in the vicinity to turn hostile.
