The London of Assassin’s Creed Syndicate is a living, breathing city, populated with a wide array of friends and foes. These are divided into six Archetypes and three Factions.
Aggressors
Aggressors include members of the rival Blighter gang and the Templars. They are shown in Red in Eagle Vision and on the Mini-Map.
Templars attack you on sight. Blighters attack you, and also attack Rooks.
Use Protectors to your advantage by drawing them closer to Aggressors. Protectors attack Aggressors if they commit crimes.
Allies
Allies include members of the Rooks and other Assassins. Depending on the memory, they follow you and help you in combat.
Allies are displayed in Green in Eagle Vision and on the Mini-Map.
Protectors
Police, Royals, and Security Guards are protectors who maintain law and order in the city. They appear as Blue in Eagle Vision and on the Mini-Map
Protectors only become hostile towards those who commit violent acts.
Protectors are powerful enemies. If you try to fight too many at once, you will likely be overwhelmed. Escape and vanish when necessary. If you need to commit a violent act, try to do it out of their view.
