Memory 01: 01 The Kings Correspondence

Head to the Assassin HQ to learn that Mirabeau was in correspondence with the king and the letters need to be recovered before they end up in the Templars hands.

After gaining control outside the palace, descend and walk through the crowds on the outskirts of the restricted area until you reach the far wall.

Climb up to the roof.

To deal with the sniper on the next tower, hop over to the other side of the building and climb along its side to get behind him. Perform an air assassination on the sniper.

Climb back up the tower and turn right to spot a Brute patrolling below. When he begins to walk away, descend and stealth kill him.

Deal with the sniper on the railing to the right.

Return to the other side of the building and look below to spot two guards patrolling in a circle and one patrolling in the middle. Wait for the two patrols to pass under Arno and perform a double air assassination.

Deal with the third guard without drawing the attention of any nearby guards or allowing him to ring the bell. You can now sabotage the first alarm bell.

Carefully head northeast and use headshots to quietly take out the two guards.

On the opposite side, take cover (press the cover button to crouch behind walls or objects) and shoot the far guard so the other walks over to check the corpse, allowing you to sneak up behind him.
