New content order
Players returning from the original need a route through what is actually new. This page separates confirmed Ubisoft additions from guide-discovered cleanup routes.
Confirmed new-content buckets
Ubisoft highlights new story arcs and missions, officers for the Jackdaw, new sea shanties, pets, photo mode, and reworked combat, stealth, parkour, naval, water, and weather systems.
Recommended order
Start with main sequences and system tutorials, recruit officers as they open, then move into treasure-map, outfit, and ship-plan cleanup once movement and naval upgrades feel stable.
What to save for later
Save full collectible routes, legendary ships, and Ultimate Ship Plan hunting for the phase after you have enough fast travel, ship durability, and region access.
Questions
Is Resynced just the original with better graphics?
No. Ubisoft lists new content and system changes, while guide outlets are already treating new routes and changed collectible logic as separate launch topics.
