01 - Stalk the Stalker | Train Hideout Memories AC: Syndicate Guide

Follow the man that is observing Agnes.

In order to start the mission, talk with Agnes in the train. Then go to the pointed location. From there you must follow the person that is following Agnes. Simply go behind the person, without losing the track of him. Once you reach a larger open territory, the main part of the mission will start.

You can surprise each sniper from the roof above.

Most of all, you can't let Agnes be killed by a sniper. There will be four of them on her road. Additionally, in order to complete the side objective you must eliminate the opponents from air. Hurry up, as each aiming is signalized with the flow of time - if you won't be fast enough, Agnes will be killed. Surprise the first enemy by jumping from the roof, then run on the same roof, jumping between buildings. Two next snipers are positioned along the next street. Climb on the very top of the roof, from where you can jump slightly below, directly on the sniper. Do the same with the last one. If you won't succeed during the first try, it will be easier during the repeat - the snipers will be positioned in the same places.

The Rooks will help you in the battle on the station.

Once the cutscene ends, go to the train station. There you will have to participate in a battle. Luckily, you will have the help of the Rooks. Use the turmoil to eliminate as many opponents as possible while remaining undetected. After a while, enemy reinforcements will arrive. Kill them all and then return to the train.

Challenges

Kill all snipers from the air - during Agnes' walk you must kill all four snipers with an aerial assassination. To do it, immediately after you spot the enemy you must climb one level above him, from where you will be able to jump on him. Each time you will have at least 10 seconds to do that, after the time is up Agnes will be shot.
