This Gang Stronghold activity is located in the eastern part of the City of London borough, just south of the Holborn Viaduct marker on the map. This memory requires us to take out eight Blighters who are residing within restricted area here. It’s a good idea to climb up to the rooftops and use your Eagle Vision to tag the enemies as soon as possible. In addition to revealing enemy locations, it will also display the optional objective – the location of the Heist Plans that we need to capture in white.

The Blighters holed up on this area are made up of a Sniper, a Lookout, the Leader and five standard melee types. All eight of them, unless disturbed or alerted are usually patrolling set routes or stationary in set locations. The Lookout can be found patrolling from north to south along the western edge of the restricted area and should be taken out early on to prevent him from calling in reinforcements.

After assassinating the Leader undetected (left). Enter the building on the southwest side of the area for the heist plans (right).

With the Lookout out of the way, we can focus on the Leader who we will want to kill undetected for the optional objective. She foolishly patrols around a small clearing with a hay stack, so feel free to use that to assassinate her from if you wish or, alternatively you can also air assassinate her from a rooftop or use throwing knives. As long as you do it undetected, the optional objective will be completed.

Before killing all of the enemies to end the memory, you’ll also want to check out the interior of the building in the southwest of the area. Inside you’ll often find a Blighter wandering about and on the second floor the Heist Plans that we need to burn for the optional objective.

Once you have completed the optional objectives, kill the other enemies as you deem fit. After they have all been dealt with, the memory will be completed.
