Tomb Raider I-III Remastered Starring Lara Croft

This achievement is earned in the 2nd level of the game, City of Vilcabamba.

In the first area, you'll have to open a front door on the wall of one of the "building" to reach a stair and jump from a "window" to another building.

Once inside, DO NOT step on the 2 shuttered floor panels and jump on the side (you can let you fall if you find the right angle to avoid loosing too much health).

Pull the block back in order to reach the ledge where the medikit is standing, while going through the open corridor the block was blocking to collect the key and the golden idol in the second room.

Get back into the first room, then jump on the ledge using the block. The final step is to jump on the panel to quickly reach the window you came from before they crash on the ground.

Once you're outside, the achievement should unlock.
