Wondering when you get certain upgrades, or whether to do side content before pushing the story? This sequence-by-sequence guide tells you what unlocks when and the optimal order of operations.
Sequence 1-2: Tutorial Phase
Cape Bonavista → Havana. Learn basic movement, combat, and sailing. You can't free-roam much yet. Do: Hunt animals on Cape Bonavista for the second pistol holster before leaving. Don't: Take on brigs or larger ships.

Sequence 3: Nassau & the Pirate Republic
Nassau becomes your second hub. Blowpipe (sleep/berserk darts) unlocks. More world opens up. Do: Sync all Nassau viewpoints, start harpooning, grab sea shanties. Don't: Tackle naval forts yet.

Sequence 4: Great Inagua & Full Open World Unlock
Massive unlock. Great Inagua becomes your permanent hideout. Second hidden blade unlocks. Lucy (Shipwright) becomes available. Diving bell unlock. Kenway's Fleet unlock. Do: Recruit Lucy, upgrade Jackdaw hull to level 2-3, start diving for elite blueprints, explore Mayan stelae. This is where serious free-roaming begins.

Sequence 5-6: Tulum & the Assassins
More story opens up, Tulum area unlocks, rope dart becomes available. The Padre (Master-at-Arms) is recruitable. Do: Recruit The Padre, upgrade to dual swords (craft the second holster), start Templar Hunt missions.
Sequence 7-8: Kingston & Expanded Naval
Kingston opens as the third major city. Forts become viable to attack. Frigates and weaker men o' war are manageable with proper upgrades. Do: Capture 2-3 forts for fast-travel and income, collect more Mayan stones, complete more Templar hunts.
Sequence 9-10: Late-Game Areas
Higher-level southern/eastern islands open. Legendary ships appear on the map (if you've explored near them). Tobias (Master Gunner) becomes available late in this stretch. Do: Recruit Tobias, complete Templar armor, finish Mayan armor if you haven't, fully upgrade Jackdaw for legendary ships.

Sequence 11-12: Observatory & Finale
Final two sequences are heavily story-focused and more linear than mid-game. Do: Finish remaining side content before Sequence 11 if you want. You can free-roam after story completion — nothing is missable.
Post-Story: Epilogue & Free-Roam
The new epilogue plays, then you return to the open world with all unfinished content available. Legendary ships, remaining contracts, Fleet, collectibles — all completable post-game.
