Challenges: Do not trigger the alarm.
You can now freely roam the map. Bring up the map by pressing the touch pad. Here you can select locations and place markers yourself for easier navigation. It's a big city, after all. Your goal is to conquer city map segments, one at a time. In order to do so you'll have to complete main missions in that map segment and defeat the boss that becomes available after doing the missions. The red haze on the map will go away after getting rid of the Templars this way in any segment. Let's get started, shall we?
As the game mentions, it's good to know that you can switch characters as long as you're not on a mission (memory). Press Options / Menu and then press R3 to switch. Jacob and Evie share money and EXP, but their gear and skills are unlocked separately. Now's a good time to buy Jacob a Noble Cane-Sword (and equip it), while equipping him with an Initiate Belt. Equip Evie with a Thrifty Cloak.
First off, let's start with a simple mission. Select Child Liberation: To Catch An Urchin from the right side of your map and mark it. If done correctly, a marker now appears in the world so you can easily find the starting point for this memory. You'll have to rescue several children - three groups of three - from the Blighters.
Make your way to the large building in the distance and avoid any nearby enemies. Scale up the walls until you reach the roof. From here you can find an open entrance on one of the lower roofs. Quietly take out the thug here and climb the railing. Scan the entire area with Eagle Vision (preferably Eagle Vision 2, so you can see and mark through walls). There's a (yellowish glowing) leader on the level below you. When he turns his back towards you, drop down one level and assassinate him. Quickly throw a knife or two at the other thug in the distance (or alternatively assassinate him if you can do so silently). Free the three children working on the corner.
The other two groups of three children are working on the level below and the ground floor respectively. Quietly dispatch the nearby thugs and free them to complete this mission. If no one sounded the alarm, then great; this completes the optional objective.
