Flooded Archives - Greek Fire Depot North Side (Part 3)

Follow the hallway to a balcony overlooking the pool, where you'll find an Explorer Satchel (1/1), which reveals the locations of this level's survival caches. (If you followed this walkthrough, you've already found one cache in the room below.)

Turn around and head back the way you came. At the end of the hallway, turn right and drop into the dark area with the wooden floor.

Go around to the back of the dark area and jump over the opening in the floor. (This sequence is not shown. It's just the reverse of what you did in the previous steps.)

Climb up into the hallway on the other side of the wooden-floor, turn right...

...and follow the hallway to emerge outside overlooking the pool.

Jump over to the balcony ahead on the left.

NOTE: These screenshots were taken during a playthrough when I tried things in a different order. If you follow this walkthrough the area ahead will not be on fire at this point.

At the front of this balcony on a small pedestal is a document (4/5), The Greater Good from the Voices of Invasion series (Mongolian). From here, continue along the balconies across the front of this building...

...all the way around to the far end...

...to find a monolith (1/1). Read the Greek inscription to reveal the locations of 2 coin caches on your map. There is a third, but it's in the unexplored area to the south. You'll see it when you get there.
