Okay - I'm stumped. There don't seem to be enough boxes in Thousand Souls Delta to achieve the task of covering the pressure plates.

There are 14 (indicated by red squares in the image) pressure plates to cover and 13 boxes that are free. The boxes with a CYAN X are impossible to use based on their starting positions.

In diagram 1, because Lucas has to move the barrel twice just to enter the room, that elimiates the first two crate/barrel objects. In order to leave the room I presume I have to get to the position in diagram 2 at the right. Where Jax is on the starting postion, but this reduces the number of boxes available down to 12 to cover 14, and Jax isn't clever enough to cover 2 at once.

In diagram 3, I had the choice of either pushing the barrel (marked as #2 in the first diag) which leads me to eliminate the barrel for useage, or I push the top box (#1) and then shove it back once I am past it. But this forces me to move #3 as Lucas cannot move diagonally. It puts me in diagram 4. If I move #4 right one it disables further use of the box. If I move #3 instead I get trapped with only diagonal moves available and Lucas cant move that way.

I can get to the jax icon easily enough, but I consistently end up 2 boxes short because at least one becomes unmovable.

What am I missing here?
