The St. Giles Rookery Gang Stronghold is located in the northeastern part of The Strand borough, just next door to the east of St. Pancras Station. Completing this Gang stronghold activity requires us to take out 15 Blighters who are guarding this restricted 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 as there are quite a few of them. In addition to revealing enemy locations, Eagle Vision will also display the optional objectives – the Rooks that we need to capture highlighted in white.

The Blighters holed up on this area are made up of three Snipers, three Lookouts, the Leader and eight standard melee units. All 15 of them are usually patrolling set routes or stationary in set locations unless you upset them or they become alerted.

As per usual, we’ll want to focus on taking care of the three Lookouts first to prevent them from calling in reinforcements. The first Lookout can be found patrolling back and forth along the southern edge of the restricted area and should be taken out first. The second Lookout can be found patrolling from east to west and back again near the northeast corner of the restricted area. The third Lookout patrols in front of the freestanding building in the northwest corner of the area.

Tag the enemies using Eagle Vision from the rooftops (left). The first Rook is located in the courtyard (right).

Using throwing knives from rooftops is a great way to take out isolated bad guys. We can also sneak up and assassinate most of the enemies after observing their patrol patterns.

There are two Rooks whom we’ll we need to rescue for the optional objective. Note that it’s a good idea to rescue them with only 4-5 enemies left though as if you free them, they’ll want to help you out and attack nearby enemies. As they can be a little delicate, this means you’ll need to keep an eye on them and try to draw enemy attacks from the Rooks to keep them alive. If either of them dies, you’ll fail the optional objective.

The first Rook can be found in the western side of the central courtyard area between all of the buildings. The second Rook is located inside the central freestanding building along the northern wall on the second floor.

Other than those pointers above, simply kill the enemies as you see fit. Once they are all dead, the memory will be completed.
