Escape your pursuers
When your notoriety meter next to the minimap goes red, this indicates that enemies are actively chasing and fighting you. The key to escaping is breaking their line of sight with you, normally by running around buildings or behind trees, at which point your meter will turn yellow. You can keep running until you exit the marked area on your minimap, but it’s much easier to find a hiding place such as a hay pile or cart and dive in. If you successfully made it into this cover undetected your meter becomes blue, then it’s just a case of waiting until your enemies lose interest. If any get too close while still investigating, a quick push of Square should silently assassinate them without giving yourself away.
