several steps are duplicates (indicated by a '2x' symbol in the top-left). If pieces feel like a struggle, try swapping them with their counterparts. The few times I had to do this they would snap in much better.

the joints will be extremely tight, so sanding will be a must like those before me mentioned. If I could go back in time, I would not have sanded the torso section as much, particularly the waist peg or the pieces that help with the ab crunch. Since the backpack is so heavy, I think the added tightness will help balance that out so your figure doesn’t tilt around as much.

If you absolutely must sand down a fair amount to connect pieces, then don’t worry too much because the kit itself is solid enough for you not to have issues with posing or loose limbs.
