Once you have completed the initial memory missions for both Evie and Jacob, you’ll arrive in London and as with many open world games, you’ll be pretty much free to explore the city as you see fit. There is a lot to see and do, so take your time and enjoy the experience!
During memories (read missions) our assassins will be locked into a specific time of day and are required to achieve a healthy variety of different objectives in order to finish them. As you progress through the story memories of the campaign, you’ll obtain additional items and abilities and be able to undertake more London Story side-missions as they become unlocked.
Between missions you’ll be in free roam, during which time you can undertake an assortment of associate activities to liberate boroughs from Templar influence, find and undertake side-missions, visit the Train Hideout (your own personal train!) and hunt down collectibles to your heart’s content.
