Silver Chest
After collecting the previous chest, continue ahead in a linear path and you will reach the Hydraulic Testing hall. Defeating all the enemies there will open the exit door. Climb on the shipping containers and from there jump to the broken staircase to reach the exit door. Exit the hall and you will find the silver chest inside the room on the left side. Open it to get the Fox-Blade blueprint.
Gold Chest
After getting the silver chest, go back out and continue head. Jump through the hole in the wall and then jump on the hanging platforms to reach the catwalk on the other side. Proceed ahead and jump through the hole in the floor in the next room. You will fall into Polymer. Emerge from the Polymer and you will find a locked door there. Pick up five balls from this room and throw them into the sockets above the locked door as shown in the picture below. Now go to the red switch nearby and press it to open the door. Go though this door to reach a puzzle area.
As you enter the area, go through the door on the left side. Climb up the wooden ramp inside the room and pick up the ball ahead as shown in the picture below. Now go back out and climb up the stairs. Insert the ball into the socket kept in front of the stairs.
This will move a structure and bring it in front of you. Jump on the ledge of this structure. Move to the opposite end of the ledge and from there, jump to the pipe on the other side as shown in the picture below.
From the pipe, jump to the ledges on the wall next to it. Then move on the ledges to reach the platform in front of the airplane as shown in the picture below.
Climb up the wooden ramp there and pick up the ball as shown in the picture below. Go down the ramp and insert this ball into the socket there.
This will move a structure and bring it in front of you as shown in the picture below. Jump on the wooden platform at the bottom of this structure. Then use the ledges to climb to the top.
Once you are at the top, take out the ball that you inserted into the socket before. This will get the structure moving back to its previous position. Drop the ball down. When the structure reaches back to its old position, jump down to the wooden platform at its bottom as shown in the picture below. From there, jump on the ledges to reach the door as shown in the second picture below. Proceed ahead to reach the gold chest. Open it to get PM – Reinforced Bolt Frame and Swede – Blade blueprints. Go out of the room and stand on the platform on the left side. It will take you back to the top.
