The Frozen City: Part

From the Challenge Tomb entrance, follow the northern wall west to the large, domed tower. In the courtyard south of it, silently take down the two patrolling Deathless soldiers.

Enter the building west of the tower to find a Mushroom and a chest with Relic [04/10 – Spurs]. In the courtyard center, find the crane structure; at its base is Coin Cache [03/03].

On the south wall near a market stall, destroy the metal barrier with explosives. Inside, find Document [04/08 - Mongolian], Cloth, and Magnesite Ore.

Look at the domed tower. Burn down the cloth barrier on the south side at ground level with a Fire Arrow. Inside, find a chest with Relic [05/10 – Kitezhian Silver].

From the Relic room doorway, use a market stall to jump to the hanging crate. Climb it, then use the adjacent beam to leap to a handhold on the domed tower. Climb to the top using beams, handholds, and grapple axes. On the upper platform, find Document [05/08 - Mongolian] and Bell [For Whom the Bell Tolls 04/05].

Use the zip line at the tower's top to reach the objective marker at the gate. A scene will play.

When you regain control, a trebuchet will occasionally fire. Keep an eye on its direction.

Halfway down the stairs on either side of the gate, destroy Statues [Vandal 02/08 and Vandal 03/08]. At the bottom center of the stairs, find Document [06/08 - Mongolian]. Above and right of the Document, find Banner [Banner Wars 06/08].

Return to the top of the stairs and use the zip line to reach a building to the south. Kill any Deathless soldiers and shoot the Archer on the distant balcony, using the Greek Fire vessel.

In this building, find a chest with Relic [06/10 – Flint Striker]. From here, look along the right wall to spot Banner [Banner Wars 07/08] on the next building south.

Drop down via handholds near the Relic and kill Deathless melee soldiers in the northwest corner of the building. Find Survival Cache [06/06] at the building's base.

Return to where you dropped and use the grapple axe to climb back up. Climb to the roof and use the rope to reach the building to the south. Drop into the small room near the top. On the right, destroy the wall with a firearm. Inside, find Relic [07/10 – The Pagan God].

From this building, jump to the small elevated platform below and right, then scramble up to the next building's upper level.

Fight Deathless Soldiers manning the trebuchet and archers. Use Greek Fire vessels to help eliminate them. There are three archers by the trebuchet and one on a rooftop to the left.

Fight across the rooftops until you reach the trebuchet.

Drop down and fight a shielded Deathless Soldier. Use Broadhead Arrows on the weak wood wall below and west of the main platform, then the ice wall, to climb to the top.

On the platform, kill the two waiting archers using Greek Fire or gunfire. Look on the far side for a cylinder of reagents. Scramble up to the trebuchet and kill one final melee soldier.

Use the wheel mechanism on the platform to control the trebuchet.
