Tomb Raider I-III Remastered Starring Lara Croft

This needs to be done in the third level, Bartoli's Hideout.
Follow the level's path up until the library, after the chandeliers area.
On that library, kill the enemy and go to the room he just got out.
Climb the bookcase, so you can use the lever to open one library door.
Follow that path, climb another bookcase, jump on the platform and climb another bookcase (!).
Break the window, slide down the slope jumping on the balcony ahead.
From there, jump to the little roof near the walls with the door.
Don't fall on the water or jump on the shack/boathouse yet!
Follow this wall to the very end, and jump-grab to the roof of the shack.
On the other side of this roof, there's an opening on a wall. Jump over there, and grab the Uzis!

Tomb Raider II - Bartoli's Hideout (Level 3)

After climbing out of the highest window of one of the library wings, slide backwards to grab the ledge of the red awning then climb and immediately backflip to the stone platform. From here make a running jump to the tiled awning and then another jump to the brick wall.

Make your way right to the end of this wall. Make sure you're a little bit back from the very end then line up a running jump to the left to grab the boathouse roof (if you're lined up with the very end you won't make the grab). Traverse to the other side of the roof and perform a diagonal running jump onto the smaller brick wall. Drop down into the dark alcove to find the Uzis.
