Sequence 09 Walkthrough
Last updated: July 2026
Sequence 09 opens the Observatory storyline. Day One Patch 1.002 fixes a rare NPC trigger bug in memory Trust Is Earned — ensure you are on update 1.002.
Memory 1: Observatory Clues
Gather intelligence through split objectives on land and sea. Use Observe mode to plan dual-pronged approaches.
Memory 2: Trust Is Earned
If an NPC fails to trigger escort behavior, verify Patch 1.002 is installed — this was a known day-one bug. Reload from checkpoint after patching if stuck.
Memory 3: Deep Dive Assault
Combine underwater entry with ship bombardment. Dive-anywhere lets you bypass surface guards entirely if lung capacity is upgraded.
Resynced tailing and eavesdrop missions in Sequence 9 use grace meters instead of instant failure — see Observe mode before stealth memories. Continue to the next sequence in order or explore legendary ships if your Jackdaw is fully upgraded.
