Part 1: Infiltrate
- Perform 3 ledge assassinations.
- Don’t lose more than 33% health.
- Perform a three kill combo streak.
- Complete all optional objectives in a single playthrough.
From the start we want to climb the cliff immediately in front and continue up to the top of the adjoining tower above. Ledge assassinate the guard (1/3) standing up here. Climb up on top for a scene.
Part 2: Escape
Following the scene, kill the guard that appears. After the roof caves in, climb up the fallen walkway and then out of the newly made hole near the roof. Jump across to the next roof and continue to the left. Use the crates to hop up to the beams and continue through the attic. When it drops, hop through the window and into the adjacent building.
Kill the guards in here, being sure to try for the three kill combo streak to complete the optional achievement for doing such and ensuring you don’t lose more than 33% of your health.
