Override Subroutines is a learnable Machine Master skill in Horizon Forbidden West.

Use

Unlocking this skill enables Aloy to choose between two different modes when overriding a machine: Aggressive or Defensive. Defensive is the default behavior (with or without the skill) and the machine will stay close and protect Aloy. They will not attack unless an enemy is alerted and will typically focus on the same target as Aloy. Aggressive behavior causes the machine to seek out and attack any enemy it can detect.
