Memory 03: 03 The Observatory

Set your weapon to unarmed for the optional objective.

Enter the first jungle zone. There are three guardians here, all in stalking zones. Use Eagle Vision to locate them and incapacitate them from stalking zones.

Follow the stream uphill to the second zone. Use wooden watch platforms and tree branches to drop down behind guardians and incapacitate them.

Backtrack up the river, climb a tree, and use wooden lookout platforms and branches to reach and incapacitate the remaining guardians in this zone.

Head up the river to the third zone. Use treetop paths and wooden lookout platforms for vantage points. Incapacitate the guardian on a platform first, then use Eagle Vision and platforms/branches to drop behind and incapacitate the others.

If you have completed the optional objective of incapacitating five enemies from stalking zones, you can now use open combat, but keep your fists equipped.

Enter the cave. There are 10-12 guardians here, not hiding but in plain sight on the ground floor, ledges, and side-tunnels. Use Eagle Vision to locate any remaining enemies as the search area narrows.

Return to a jungle setting. Follow the path to the right. Cross the fallen tree bridge and incapacitate the guardian in the stalking zone.

In the clearing before the black stone building, incapacitate the three remaining guardians: one patrolling, one on a higher platform, and one in a stalking zone behind the building.

Follow your allies to the door of the main building.

Pick up the chest and follow your friend through the building to a circular room with a glowing panel. Place the chest below the panel. A cut-scene will follow.

After regaining control in the water, turn around and climb the blocks to reach the circular platform with the glowing panel.

Remember to pick up the Animus Fragment during the escape.
