1/6 - Bronze
The bronze statue is going to be located on the roof of the first building. Instead of using the grapple, head on to the right (upper) platform. You will come across a single crate (#1). Enter the Accurate Aim mode and destroy it. You may pick up the reward (#2).

The second statue is beneath the small stairs, next to the bike.

3/6 - Bronze
The next bronze statue is located on the other side of the bridge. Head on to the lowest platform. Keep moving forward. The statue is hidden in a small crate.
4/6 - Bronze
Once you've reached a small staircase, head on to the lower level. Destroy a crate and pick up the reward.
2/4 - Silver
Don't leave the staircase just yet. This time you will have to reach the top floor. There are some large pipes on your right. You should be able to make a jump towards a narrow ledge (#1). Start moving right. Now you will have to reach some new pipes. The reward will be located on your left (#2). Pick it up and return to the staircase.
3/4 - Silver
You will have to reach the room with a big screen. Take care of the remaining enemy soldiers. After that, head on to the nearest balcony. Open the left door by kicking it (#1). There's a silver reward here (#2). Take it.
5/6 - Bronze
The next bronze reward is located in one of the corners (the left one if you're standing by the entrance). It's a small room with a lot of glass. Destroy the crate and pick up the statue.
6/6 - Bronze
Once you've reached a small museum, take care of the remaining enemy units. After that, turn around and head on to the left corridor (#1). You will come across some stairs along the way. Lara will find herself on an upper balcony. The statue is hidden in a small crate (#2).
4/4 - Silver
The last silver statue is in a small room that's located on your left (#1). You might have some problems locating it. Don't worry... it's there. ;-) Head on to the middle locker and open it. Pick up the statue (#2).
1/1 - Gold
The gold statue will be well hidden, however it's very easy to get it. Don't use the elevator that leads to the boss fight. Instead, turn right. There is a long corridor here. Once you're in an office, pick up some of the guns. You should be more interested in a red box. Start pulling it towards the elevator. Once you're there, push it so it falls down (#1). Get back to the lower level and pick up the gold statue (#2).
