This Gang Stronghold activity is located in the eastern portion of Lambeth borough near the edge of the map and it requires us to take out seven Blighters guarding the area. 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 Rook 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 four standard melee types. All seven of them are usually patrolling set routes or stationary in set locations, but you’ll want to watch out for the lone rooftop Sniper in the eastern side of the area and take her out at the first opportunity. The Lookout can be found patrolling along the northeastern corner of the restricted area and should be taken out early on to prevent him from calling in reinforcements.

Use Eagle Vision to mark the enemies (left). The leader can be found by the captured Rook (right).

The Leader whom we’ll need to take out undetected for the optional objective hangs out on the eastern side of the restricted area and will patrol from north to south past the Rook prisoner (who we’ll also need for an optional objective). Once you are in range, either head shot the Leader with a throwing knife (if you are sure it will kill him) or air assassinate him from above.

Once the Leader is down, free the Rook prisoner and deal with the other enemies as you wish. After killing them all, the memory will be completed.
