How do I build the Mission Models?
- Sort the LEGO element bags (found in your Challenge Set box) by bag number. They are labeled.
- Match the bag numbers with the corresponding bag numbers below.
- Open the correct pdf files and have an awesome time assembling the models. We strongly recommend opening one set of bags at a time so elements are not mixed up.
- Have fun!
