Memory 06: 06 The Crate Escape

From your starting position, immediately use the Rope Launcher to get yourself up onto the roof of the building directly ahead.

Once on the roof, move across until you have a clear view of the target cart below.

Use the Rope Launcher again to cross over to the sniper platform on the opposite side. Take out the sniper positioned there.

Look down and behind the cart; you'll spot an enemy standing near a fire barrel. Equip a hallucinogenic dart and shoot the fire barrel. This will make the enemy go berserk and attack any nearby Thugs.

Now you have two options: either help the berserk enemy take out the other Thugs in the area before you sneak into the cart, or wait for the distraction and sneak over to the cart yourself and hop into the back while the enemies are occupied.

Once you're inside the cart and inspect the chest, a cutscene will play.

After the scene, you'll be in the back of a carriage driven by Jacob. For about a minute, you'll need to defend yourself from a barrage of enemy carriages.

Keep a close eye on your mini-map for the red enemy indicators. When they get close enough, aim and shoot. Hitting the horses will often tip their carts over, and shooting the enemies directly will have a similar effect.

Don't worry too much about running out of ammo, as you'll have unlimited shots. However, be aware that the reload time is quite slow.

Eventually, Jacob will bring the carriage to a stop. As soon as this happens, quickly get out and run to the objective marker on the side of the road to complete the memory.
