Golden comp chapter 3.1 how do i stop rodger there is a box on top ledge but cant reach it please help?

Instead of continuing up which you will need to do later in order to complete the chapter, you need to make your way down to the lower level. Just before you reach the mechancial baskets, which you need to activate to stop Roger, you will come across a pile of 5 or so boxes, use pan to smash these and you will find the key to open the door which has now been revealed. Enter this door and you will find the lever to activate the mechancial baskets, this will complete your misson and you will then be able to climb up to the higher level to finish the chapter. I hope this helps
